Preheat oven to 350 degrees **Or cook on a baking pan on the grill** Place the sliced zucchini on a baking pan coated with vegetable spray and sprinkle with salt and pepper. Mix all remaining ingredients in a small pan on medium-low heat for 5-10 minutes. Sprinkle on the top of each zucchini slice. Bake for about 15-20 minutes, until cheese is melted and begins to brown slightly. Enjoy your summer!!!
