Stuffies are a New England local food. They are stuffing and clam meat, served on a clam shell. You can buy them in supermarkets and seafood stores all over the place. Microwave for 45-75 seconds. Yummy. They come in regular and spicy, but the spicy ones are only medium hot.
Stuffies sold at Portuguese shops included charizo (a Portuguese sausage) as well as clam. Although orange in color, they are not spicy.
