Preheat your oven to 375°F (190°C) and grease a baking dish with cooking spray.

In a medium bowl, whisk together 6 large eggs with a pinch of salt and pepper.

In a separate bowl, mix the crumbled cooked sausage, diced bell peppers, and chopped green onions.

Heat a skillet over medium heat, add oil, and scramble the eggs until fluffy and slightly undercooked, about 3-4 minutes.

Lay out 6 corn tortillas in a greased baking dish, fill with scrambled eggs and sausage mixture, and sprinkle with cheese.

Bake in the preheated oven for approximately 15 minutes until cheese is bubbly and golden brown.

Let cool for a couple of minutes, then serve topped with salsa or avocado slices.
