Preheat the oven to 375°F (190°C).
Lightly grease a 9-inch deep-dish pie pan or oven-safe skillet with 1 tablespoon of olive oil.
Place two tortillas in the pan, pressing them into the bottom and sides to form a crust. Overlap and press to fit snugly.
In a medium skillet, heat 1 tablespoon of olive oil over medium heat. Add diced onion, green bell pepper, and red bell pepper. Sauté for 4-5 minutes until softened.
Add cooked ground turkey sausage to the skillet with the vegetables and stir to combine. Remove from heat.
In a large bowl, crack the eggs and whisk together with salt, black pepper, and garlic powder until well combined.
Spread half of the shredded cheddar and mozzarella cheeses evenly over the tortilla crust in the pan.
Add the cooked sausage and vegetable mixture evenly over the cheese layer.
Pour the whisked eggs evenly over the sausage and vegetables.
Sprinkle diced tomatoes and the remaining shredded cheeses on top.
Bake in the preheated oven for 20-25 minutes, or until the eggs are fully set and the cheese is melted and bubbly.
Remove from the oven and let cool for 5 minutes.
Sprinkle chopped fresh parsley over the top before slicing and serving.
