This is my spin on the famous white clam pizza hailing from New Haven, Connecticut. The addition of grilled sweet onions, cherry tomatoes, and parsley on top of the crispy whole rye crust take things to a new level. While you can use any grateable cheese, like parmesan or romano, I prefer aged asiago. You can also add mushrooms or capers, and substitute with your choice of protein, such as shrimp, lobster, chicken, or pork belly.
