Preheat your oven to 350 degrees. In a large, spouted bowl, whisk the 10 eggs, milk and parmesan cheese. Season with salt and pepper and set aside.
In a large oven-proof skillet, over medium heat, add the olive oil, red peppers, jalapeño and onion. Cook until they become slightly soft, about 2-3 minutes. Add the garlic and cook until fragrant, about 30 seconds.
Add the zucchini and spinach. Cook until the spinach is wilted, about 2-3 minutes. Then add the cooked turkey sausage and taco seasoning. Stir well to make sure that all of the ingredients are coated in the seasoning. Remove your skillet from the heat.
Whisk the egg mixture one last time and then pour it over top of the veggies and sausage, making sure that the eggs are evenly distributed.
Bake in the oven for 15-18 minutes until the eggs are fluffed up and the center is set. Let it sit for a minute or two before slicing. Top with fresh chopped cilantro (optional). Enjoy!
