1 Preheat the oven to 400 degrees. 2 Heat a skillet over medium high heat. Add the sausage and cook until no longer pink, breaking it up as it cooks. Remove and set aside. 3 Add the olive oil to the pan. Once hot, add the butternut squash and red onion. Cook for 8-10 minutes until squash and onion are tender, adding 1-2 tablespoons of water if burning. Add the salt, garlic powder, oregano, and pepper. Stir together. Add the spinach and cook until it wilts, 1-2 minutes. 4 Whisk together the eggs. Add the sausage and butternut squash mixture to a baking dish sprayed with cooking spray. Pour the eggs over top. Bake for 25-30 minutes until eggs set and are cooked through.
