Chop onions, bell peppers, and tomatoes. Grate cheese if necessary.

In the same pan, sauté onions and bell peppers until softened. Add tomatoes and cook for an additional minute.

In a bowl, whisk eggs with salt and pepper. Pour into the pan with vegetables and scramble until cooked through.

Lay out a tortilla, spoon some of the egg and vegetable mixture onto the center, top with cheese, and crumbled bacon or sausage. Fold the sides of the tortilla over the filling and roll up tightly.
