Place the beef in a skillet over medium heat. Cook until evenly brown. Drain grease. Mix in sloppy joe seasoning.
Press 1 can of refrigerated crescent roll dough in the bottom of a 9x13 inch baking dish. Layer with ground beef. Sprinkle mozzarella cheese and Cheddar cheese over beef. Spread evenly with sauce. Top with remaining crescent roll dough.
Bake 40 minutes in the preheated oven, until top is golden brown.
