Place chicken patties on a baking sheet. Bake patties according to package directions. Meanwhile, place sauce in a saucepan and heat through over medium heat.
Remove baking sheet from oven; turn chicken patties over. Spoon about 1/4 cup sauce over each chicken patty. Top each with cheese. Return to oven and bake for 4 to 5 minutes more or until cheese melts.
Serve chicken patties over spaghetti with remaining sauce. Makes 4 servings.
