Preheat oven to 400 degrees Farenheit.
Line a baking sheet with foil and spray it with nonstick cooking spray.
Slice your zucchini into 1/4 inch slices and line them on the sheet.
Top each zucchini slice with sauce, cheese, and then toppings.
Place them in the oven and bake for about 10-15 minutes or until the zucchini is tender.
