Put crackers into gallon freezer bag. Using a rolling pin, smash and roll the crackers into breadcrumbs. In a bowl place ground beef, onion, garlic powder, and salt and pepper to taste. Sprinkle cracker crumbs over beef.
Gently mix all ingredients together until evenly mixed. Do not over mix. Separate meat into five sections, form sections into burgers and place on a plate. Then cook either by grill, or grilling machine to desired doneness. Top with favorite cheese if desired. I do not recommend cooking them in a pan because the grease can not drain away from the meat. Serve plain or dress up.
