1. Preheat oven to 375°F (190°C). Lightly grease a large rimmed baking sheet with olive oil or cooking spray.

2. In a large skillet over medium heat, cook diced bell peppers and onion until softened, about 5-7 minutes. Add cooked sausage or bacon and stir to warm through. Add baby spinach and cook until wilted. Remove from heat and set aside.

3. In a large bowl, whisk eggs with milk, salt, and pepper until frothy.

4. Pour egg mixture evenly onto prepared baking sheet. Scatter cooked veggie-meat mixture evenly over eggs.

5. Bake for 15-20 minutes, until eggs are set and slightly moist on top. Do not overbake.

6. Remove from oven, immediately sprinkle shredded cheese over the hot eggs. Let sit for 1-2 minutes to melt.

7. Use a knife or pizza cutter to cut egg mixture into 10-12 rectangular portions.

8. Warm tortillas briefly (microwave 15-30 seconds or dry skillet) to make pliable. Place one egg portion in center of each tortilla. Fold in sides, then roll tightly from bottom up.

9. Serve immediately or cool completely for storage.
