2 pounds ground beef
4 slices Swiss cheese
1 small onion, finely chopped
2 to 3 jalapeno peppers, seeded and finely chopped
4 hamburger buns, split and toasted
Lettuce leaves and ketchup, optional
Seed the Jalapenos and cut them into pieces or rings. Bake at 350 in a shallow dish for about 6-8 minutes or until tender.
Shape beef into eight thin patties. Top four patties with cheese, onion and jalapenos. Top with remaining patties; press edges firmly to seal.
Grill, covered, over medium heat or broil 4 in. from the heat for 8-9 minutes on each side or until a thermometer reads 160° and juices run clear.
Serve on buns. If desired, serve with toppings.
