Can I prepare this casserole ahead of time?

You can assemble it the night before and refrigerate; just bake fresh before serving for best texture.

Are there vegetable options to add more nutrition?

Diced spinach or mushrooms can be added for extra flavor and nutrients, sauté them with the peppers and onions.
