How To make Beef Burgers with Caramelized Onions

1/3 c Bulgur
2 ts Olive oil
4 c Onion(s), sliced (4 med)
2 ts Sugar
2 ts Balsamic vinegar
Salt to taste 3/4 lb Lean ground beef
2 tb Tomato paste
1/4 c Parsley, chopped
1/4 ts Black pepper
4 Hamburger buns
Split and toasted Lettuce In a small bowl, combine the bulgur with 1/2 cup warm water; let stand for 30 min, or until the bulgur is tender and the water is absorbed.
In a large non-stick skillet, heat oil over low heat. Add onions and sugar; saute until the onions are tender and dark golden, about 15 min. Stir in 1/4 cup water and vinegar. Season with salt and keep warm.
Prepare the grill or preheat the broiler. In a medium bowl, combine the bulgur, beef, tomato paste, parsley, 1/2 tsp salt and pepper; mix thoroughly but lightly. Shape into four 3/4-inch-thick patties. Grill over high heat or broil on a lightly oiled rack until browned and cooked through, about 5 min per side. Blot the patties with paper towels. Place each patty on a bun, top with the caramelized onions and garnish with lettuce. eating Well Recipe Rescue Cookbook ISBN 1-884943-01-2 pg 149
