Stuffed breads. Take one pizza dough, roll as you would for a pizza, stuff with choice of meats and cheese combinations. Roll, bake, cut serve with appropriate dipping sauce. Some examples, pepperoni and provolone, marinara dipping / ham, Swiss, mustard or dressing / Reuben, corned beef, Swiss, saur kraut(strained) mustard or Russian dressing.
Mini meat balls, choice of marinara, Swedish, BBQ.
Bruschetta on toast squares.
Endive stuffed guacamole.
Bacon wrapped anything! (Water chestnuts are cheap) covered in BBQ sauce.
Personal quesadilla. (take tortilla spread cheese, roll, bake, slice) salsa dip.
Mac-n-Cheese bites. Stuff small crescent roll squares with a spoon of pre-cooked and refrigerated Mac-n-cheese and bake.
Mini/Individual tuna melts.
California rolls with artificial crab sticks. (Depends on your sushi rolling skills)
Hope these give you some ideas!
