Start with: A large cheese pizza. (Ask for it unsliced and, if possible, slightly underbaked.)
To make: Avoiding the crust, cut out mini pizzas with round cookie or biscuit cutters. Heat the rounds at 400º F for about 5 minutes. Top with slices of olives, marinated mushrooms, chopped prosciutto, an anchovy fillet, or fresh herbs (such as basil, flat-leaf parsley, rosemary, thyme, or oregano).
