For a spicier version, use spicy sausages or add a pinch of red pepper flakes. You can also mix in some bell peppers or onions for added flavor and texture. If you prefer a creamier dish, stir in a cup of sour cream or cream cheese before adding the cheese topping. For a vegetarian version, substitute the sausage with a plant-based alternative or simply add more vegetables like zucchini or mushrooms.
