Start by removing the chorizo from its plastic packaging. You'll see the meat is encased in a thin reddish casing. Using a small paring knife or even your fingernail, make a small slit along the length of the chorizo. Gently squeeze the meat out of the casing into a bowl, almost like squeezing toothpaste. If the casing is stubborn, run it under warm water for a few seconds and try again. Discard the casing. Place your large skillet over medium-high heat for about one minute until it's hot. You'll know it's ready when a drop of water sizzles on contact and immediately evaporates. Add the chorizo meat directly to the pan—don't add oil yet; the chorizo will release its own fat. Using a wooden spoon or spatula, break the chorizo into small pieces as it cooks. You're not creating a paste; you want small crumbles about the size of peas. Cook for 6 to 8 minutes, stirring occasionally. What you're listening and looking for: the sizzle should be steady and the meat should turn from bright red to a deeper reddish-brown. You'll see the fat starting to separate from the meat—that's the chorizo rendering and releasing its flavorful oils. This is exactly what you want. When the meat has lost most of its raw pink color and is mostly brown, transfer it to a clean plate using a slotted spoon. Leave as much of the fat in the pan as possible.

This is where the magic happens. You're going to use that flavorful chorizo fat to cook your vegetables, which is a technique called "cooking in fat" or using a rendered meat foundation. It's how professional kitchens build deep flavor. Keep the skillet on medium heat. Add the 2 tablespoons of olive oil to the chorizo fat already in the pan. You should have about 3 tablespoons of combined fat—if it looks like much more, you can carefully pour some off, but don't obsess about it. Tilt the pan so the fat coats the entire bottom. While the oil heats for 30 seconds, prepare your vegetables: Dice your ½ white onion into small ¼-inch pieces. You're looking at roughly ½ cup of diced onion. Remove the stem and seeds from the red bell pepper and cut it into small ¼-inch dice—you want about ¾ cup. Cut your three Yukon gold potatoes into ½-inch cubes. Don't stress about perfection here; you're aiming for consistency so everything cooks at the same rate. Add the onion and bell pepper to the hot fat and stir immediately. Listen for the sizzle—if the pan is hot enough, you'll hear it right away. If not, wait 20 more seconds. Add the potatoes directly to the pan along with ½ teaspoon salt and ¼ teaspoon pepper. Stir everything together so the vegetables are coated in the fat.

Set a timer for 10 minutes. Cook over medium heat, stirring occasionally—about every 2 to 3 minutes. You're not stirring constantly; you're just checking in and making sure nothing is sticking to the bottom. What you'll notice: the onions will become translucent (you can see through them), the bell pepper will soften, and the potatoes will gradually turn from firm to tender. Here's the beginner trap: Many people raise the heat to speed this up. Don't. Medium heat allows the potatoes to cook through without the outsides burning. If you're at a rolling boil or the vegetables are browning too fast, lower the heat slightly. After 10 minutes, pierce a potato piece with a fork. It should slide through with almost no resistance. If it still feels firm, cook for another 1 to 2 minutes and check again. Once they're tender, add the 2 cloves of minced garlic directly to the pan and stir. Cook for exactly 1 minute—garlic burns quickly, so you're just letting it bloom and release its aroma without browning it.

While your vegetables are cooking (sometime around minute 5 or 6), prepare the eggs. Crack 8 large eggs into a medium mixing bowl. Add 3 tablespoons of whole milk. Using a whisk or fork, beat them together for about 30 seconds until the mixture is uniform and the yolks are fully incorporated. You should see no streaks of yolk—it should look like pale yellow liquid. Why add milk? Milk adds fat and moisture, which creates fluffier, more tender scrambled eggs. Some people use cream for even richer results, but whole milk is the everyday standard and works beautifully. Set this bowl aside near your stovetop so you're ready to cook the eggs as soon as the vegetables are done.

Once your vegetables are tender and the garlic has cooked for 1 minute, transfer everything to a plate to join the chorizo. You don't need to clean the skillet—a little bit of residual flavor is welcome here. Place your medium non-stick skillet over medium-low heat. Add 2 tablespoons of unsalted butter. You'll see it start to foam and smell slightly nutty. Once the foaming stops and the butter is melted and liquid, pour in your egg mixture. Don't stir immediately. Let the eggs sit for about 15 seconds so they start to set on the bottom. Now, using a spatula, slowly push the eggs from the edges toward the center of the pan. Tilt the pan so any uncooked egg slides toward the hot surface. This technique creates larger, tender curds rather than tiny, overworked scrambled bits. Keep the heat at medium-low—high heat creates rubbery eggs, and that's the only real way to mess this up. Continue cooking for 4 to 6 minutes total, pushing the eggs gently every 15 to 20 seconds. You're done when there's no visible liquid egg left and the curds are soft and slightly creamy. It should look like custard, not rubber. It will continue to cook slightly from residual heat once you remove it from the pan, so pull it off the heat when it looks just slightly underdone. This is the professional secret to fluffy scrambled eggs.

Warm tortillas are essential for rolling without tearing. Place all 6 tortillas on a microwave-safe plate, stacking them flat. Cover the stack with a damp paper towel—just barely damp, not soaking wet. Microwave on high for 30 seconds. Remove the plate carefully (it will be warm) and check if the tortillas are pliable and warm to the touch. If they're still cool or stiff, microwave for an additional 15 seconds. Why does this matter? Cold tortillas are brittle and will crack when you roll them. Warm tortillas are flexible and forgiving. This single step prevents 90% of burrito rolling frustration. Keep the tortillas covered with the damp paper towel while you assemble so they stay warm.

Lay one warm tortilla flat on a clean surface in front of you. Imagine the tortilla divided into thirds—you're going to fill only the bottom third. This is key. Overfilling is the number-one reason burritos fall apart. Start building your burrito: Add about ¼ cup of scrambled eggs to the bottom third of the tortilla. Top with about 2 tablespoons of the chorizo-potato mixture. Add a small handful of shredded Cheddar cheese (about 2 tablespoons). Top with 2 to 3 slices of avocado. The amount you use depends on your tortilla size and personal preference, but stick to these portions until you're confident. Now comes the rolling technique. Fold the sides of the tortilla toward the center, enclosing the left and right edges of the filling. Then, starting at the bottom edge closest to you, roll the tortilla away from you tightly, using your thumbs to keep pressure on the filling as you roll. You're creating tension so the burrito stays wrapped and doesn't fall apart when you pick it up. Once fully rolled, place it seam-side down on a plate. Repeat with the remaining 5 tortillas.

Arrange your burritos on a serving plate. Top each with a generous dollop of sour cream and a spoonful of your favorite salsa. Serve immediately while everything is still warm. The eggs will stay warm for about 10 minutes; the tortillas stay pleasant for about 15 minutes. This is food meant to be eaten relatively quickly after assembly, so gather everyone and eat together.
