Nonstick cooking spray
Kosher salt and freshly cracked pepper
1/4 cup marinara sauce
1/2 cup shredded mozzarella
1/4 cup mini pepperoni pieces, optional
Italian seasoning, for sprinkling
Spray both sides of zucchini rounds lightly with nonstick cooking spray. Sprinkle with salt and pepper. Broil or grill the zucchini rounds (I used a grill pan set to medium-high) for 2 minutes on each side. Place cooked zucchini rounds on a large lined baking sheet. Top with small amounts of sauce, cheese and pepperoni pieces, if desired. Broil for an additional 1-3 minutes, or until cheese is melted, careful not to burn. Sprinkle with Italian seasoning and serve warm.
