Grilled Sourdough Cheddar Melt

Ingredients

• 2 teaspoons butter or stick margarine, divided
• Cooking spray
• 2 cups coarsely chopped onion
• 1 pound ground round
• 1/4 teaspoon freshly ground black pepper
• 1/8 teaspoon salt
• 4 (3/4-ounce) slices 2% reduced-fat processed sharp cheddar cheese
• 8 (1 1/2-ounce) slices sourdough or white bread

Preparation

1. Melt 1 teaspoon butter in a large nonstick skillet coated with cooking spray over medium-high heat. Add onion, and cook for 4 minutes or until golden brown, stirring frequently. Reduce heat; cook 10 minutes or until tender, stirring occasionally. Set aside.
2. Preheat broiler.
3. Combine beef, pepper, and salt in a medium bowl. Divide the beef mixture into 4 equal portions, shaping each into a 1/4-inch-thick oval patty. Place the patties on a broiler pan coated with cooking spray; broil 4 minutes on each side or until done.
4. Place 1 cheese slice over each of 4 bread slices; top each slice with 1 patty and 3 tablespoons onion mixture. Cover with the remaining bread slices. Melt 1/2 teaspoon butter in pan coated with cooking spray over medium heat; add 2 sandwiches to pan. Cook for 4 minutes on each side until browned and cheese melts. Repeat the procedure with 1/2 teaspoon butter and the remaining sandwiches.
