Directions

1. Mix ground beef with onion, 1/2 teaspoon Morton® Coarse Kosher Salt, pepper and three tablespoons sweet-and-sour sauce. Shape mixture into 4 patties; set aside. In small bowl, combine remaining sweet-and-sour sauce with hot mustard; set aside. Pour water into a 9-1/2x10-3/4x1-inch baking pan. Sprinkle Morton® Coarse Kosher Salt over water to form a solid layer of salt. Place patties on moistened salt.
2. Bake at 350 degrees F until desired doneness (about 25 minutes for well done, internal temperature of 160 degrees F). Do not turn patties. Transfer burgers to plate and keep warm. Discard salt bed. In skillet, saute pineapple slices and green peppers in reserved tablespoon of pineapple juice. Stir in sweet-and-sour sauce/mustard mixture; cook until pineapples and peppers are hot. Place one pineapple slice on bottom half of bun, then burger. Top with peppers/sweet and sour sauce mixture. Cover with top half of bun; serve.
