Cut the mozzarella cheese into sticks about a half-inch in diameter and four inches in length. I made eight of these for two people but you can adjust for your needs. Beat an egg with a fork and pour onto a shallow plate. Pour the breadcrumbs onto a shallow plate. Heat 2 inches of oil in a deep pot on the stove to 350 degrees or until a pinch of bread crumbs sizzle when added to the oil. Using a wire spatula, lower the cheese, two pieces at a time into the hot oil. Cook until light golden brown and remove immediately to a paper towel lined baking sheet to drain. Do not leave these in the hot oil for more than a few seconds or the cheese will melt break out of the breading. You will end up with a big mess. They cook really fast so don't turn your back on them. Finish cooking, two at a time. You can keep them warm in a 250 degree oven until all are done.
