Lots of dishes turn the inside out but this one takes the outside and stuffs it in!
1-1/2 pounds ground beef
6 thin slices cheddar cheese
1 large green pepper, julienned
1 medium onion, thinly sliced
1 medium tomato, thinly sliced
6 thin slices Swiss cheese
Salt and pepper to taste
6 hamburger buns, split
Shape beef into 12 patties. Top 6 patties with a slice of cheddar, green pepper strips, and a slice of onion, tomato and Swiss cheese. Top each with another patty and seal edges.
Broil, grill or pan-fry burgers until meat is no longer pink. Serve on lettuce-lined buns.
