Heat olive oil in a skillet over medium heat. Add diced onion and bell pepper, cooking until softened, about 5 minutes.

Add crumbled sausage to the skillet and cook until browned, about 5 minutes.

In a mixing bowl, whisk together the beaten eggs, salt, and black pepper. Pour the egg mixture into the skillet and scramble until fully cooked.

Stir in the shredded cheddar cheese until melted and combined.

Lay a tortilla flat on a clean surface. Spoon a portion of the egg mixture onto the center of the tortilla.

Fold the sides of the tortilla over the filling, then roll from the bottom up to form a burrito.

Repeat with remaining tortillas and filling.

Wipe the skillet clean and return to medium heat. Place the burritos seam-side down in the skillet and cook until golden brown, about 2-3 minutes per side.
