Mix the beef with the onion, Worcestershire sauce, ketchup and breadcrumbs. Season with salt and pepper. Mix with your hands then shape into 12 mini burgers. Grill or fry for 3-4 minutes on each side.
Meanwhile, cut the hot dog rolls or bridge rolls into thick round slices and toast under the grill. Sandwich the burgers between the bread rounds with your toppings (onions, lettuce, tomatoes, gherkins, small squares of cheddar - whatever you fancy) and secure with cocktail sticks.
