Meanwhile, in a medium bowl combine meat and seasoning. Form into sixteen 1-ounce mini burgers (about 2 tablespoons). In a 12-inch skillet cook burgers, uncovered, over medium-high heat, turning burgers once half-way through cooking. Top each potato with a burger, cheese quarter, and tomato slice. Broil 4 to 5 inches from heat for 1 to 2 minutes or until cheese is melted and tomato begins to brown. Serve with mustard, ketchup, sour cream, and/or pickles. Makes 16 snacks.
