Preheat your broiler or toaster oven. Lay out a number of Firehook Sea Salt crackers on a toaster pan or cookie sheet. Spread a tablespoonful of pizza sauce on each cracker (you can leave one end free for “a handle” if you want). Sprinkle shredded mozzarella over the crackers, trying to keep the cheese on the crackers — not the pan — if you can. Run the pan under the broiler for a minute or two, watching closely so the cheese is bubbly but not burned. Serve immediately to hungry fans.
