Place the garlic bread on the baking sheet. Spoon tomato sauce on the bread and top with any of the leftover sausage or pepper from the grinders. You can also top it with any leftover vegetables or toppings you have in your refrigerator. Sprinkle the cheese on top. Bake in the preheated oven for 15 minutes until the cheese is melted and bubbly. Slice and serve.
