Prep the veggies: Dice the bell peppers and onion finely.
Cook the veggies: In a medium skillet, heat the olive oil over medium heat. Add the diced bell pepper and onion. Sauté for about 2 minutes until they begin to soften.
Scramble the eggs: Crack the eggs directly into the skillet and add a pinch of salt and pepper. Stir together with the veggies and cook, stirring occasionally, until the eggs are just set (about 1-2 minutes).
Add sausage and cheese: Remove the skillet from heat and stir in the crumbled sausage and shredded cheese until the cheese is melted.
Assemble the burrito: On a flat tortilla, place a generous amount of the egg mixture in the center. Fold in the sides and roll tightly to form a burrito. Repeat with the second tortilla.
Optional step: If desired, place the burrito seam-side down in the skillet for 0.5 minutes on medium heat, to crisp the bottom slightly.
Serve: Slice the burrito in half and serve with your choice of toppings like salsa, avocado, or hot sauce.
