In a mixing bowl, mix ground beef and shape into 4 thick patties. Salt and pepper to taste. Generously splash top of each burger with Worcestershire sauce.
Place burgers on a hot grill and cook for 3 to 5 minutes on each side until degree of doneness is achieved. Grill buns or bread slices on top rack until lightly toasted. When ready to serve, place each burger on a toasted bun or bread slice. Top with condiments, lettuce, tomato and onion slices and enjoy with salad, chips, beans or other side dishes.
