American Pie, Peter Reinhart. Use fresh shucked clams such as manila, cherrystone, or littlenecks OR canned whole baby clams, drained. Frank Pepe Pizzeria Napoletana in New Haven is credited with inventing this pizza.
I love the new flatbreads that make a great low-calorie pizza crust. My grocery chain carries a brand called "FlatOut" in the deli area. If you can't find flatbreads, use a thin pre-baked pizza crust or use pita breads (split in half to make thin rounds). Top with chicken, caramelized red onion and Gruyere for a very fancy treat that is moderate in calories and fat.
