Manna Sandwiches – easy ground beef sandwiches with comeback sauce and swiss cheese. Hands-down the BEST sandwich we’ve eaten. Ground beef, onion, soy sauce, parsley, basil, and garlic. The sauce puts these sandwiches over the top – mayonnaise, Catalina dressing, ketchup, spicy brown mustard, and sugar. Served on hoagie buns with melted cheese. YUM!
