Method
 

Preparation
  1. Preheat your oven to 375°F (190°C) and lightly grease a 9x13 inch baking dish with cooking spray.
Cook the Protein
  1. In a large skillet, cook the ground turkey or chicken sausage over medium-high heat until browned, then drain any excess fat and set aside.
Sauté the Vegetables
  1. In the same skillet, sauté the diced bell pepper and onion for 5-7 minutes until softened. Add the sliced mushrooms and cook for 3-4 minutes, then stir in the chopped spinach until it wilts for about 1 minute.
Assemble the Casserole
  1. Spread the cooked protein evenly in the baking dish, then layer the sautéed vegetables on top. In a large bowl, whisk together the eggs, almond milk, garlic powder, onion powder, salt, and pepper until well combined.
Bake
  1. Carefully pour the egg mixture over the layers in the baking dish and sprinkle with reduced-fat cheddar cheese. Bake for 30-35 minutes, or until the casserole is set in the center and lightly golden brown.
Serve
  1. Let the casserole cool for a few minutes before slicing and serving.
