Preheat oven to 175 degrees F and heat olive oil in a large skillet over medium heat.
Add peppers and onions and cook, stirring frequently, for 7-8 minutes until onions begin to caramelize and peppers have softened. Remove veggies from pan and add steak.
Turn heat to med-high and cook steak until lightly browned, this only takes a minute or so on higher heat if sliced thin.
Place the steak and pepper blend into an oven-safe dish and pop into the oven to keep warm while you scramble the eggs.
Wipe out the skillet, if needed, and spray with olive oil spray. Combine eggs with egg whites and whisk until blended. Pour eggs into the pan and scramble until cooked through, stir in the cheese until just melted.
Place the tortillas into a storage bag with a damp paper towel or in a microwave-safe tortilla warmer and microwave for 20-30 seconds.
Fill each tortilla with an even amount of the egg and cheese mixture, then top with the steak and pepper blend. Season with salt and pepper.
Add salsa and fresh avocado, if desired, and enjoy!
Notes
Slice the steak properly. First, chill the meat so it’s easier to slice. Then, use a sharp knife to cut the steak at a slight angle into 1/4 to 1/2-inch wide stops. This method helps break down the muscle fibers, resulting in more tender strips of steak.
Consider a flavorful marinade – Elevate the taste and tenderness of your steak by soaking it in marinades like my favorite steak marinade or this Mexican chicken marinade for at least 30 minutes or overnight.
Cook the steak perfectly. It will only take a minute to sear thinly sliced sirloin over high heat to achieve a flavorful crust while keeping the meat tender and juicy. Do not leave the skillet unattended!
Streamline assembly. You can pre-cook the steak, veggies, and eggs in advance. Refrigerate the ingredients in separate sealed containers, then reheat them in the microwave before building your burrito.
How to make fluffy scrambled eggs. Whisk the whole eggs and egg whites (if using) vigorously for about 60 seconds or until foam begins to form. Additionally, cook the eggs over medium-low heat while gently stirring until just set.
