Patty Melt with Grilled Onion

Ingredients:

8 (1/8-inch-thick) slices Vidalia or other sweet onion (for sharper onion taste, use white or red onions)

1 tablespoon balsamic vinegar

Cooking Spray

1 pound extralean ground beef

1/4 teaspoon salt

1/4 teaspoon freshly ground black pepper

3 tablespoons creamy mustard blend (such as Dijonnaise)

8 (1-ounce) slices rye bread

1 cup (4 ounces) shredded reduced-fat Jarlsberg cheese

Instructions:

1) Arrange onion slices on a plate. Drizzle vinegar over onion slices. Heat a large grill pan over medium heat. Coat pan with cooking spray. Add onion to pan; cover and cook 3 minutes on each side. Remove from pan; cover and keep warm.

2) Heat pan over medium-high heat. Coat pan with cooking spray. Divide beef into 4 equal portions, shaping each into a 1/2-inch-thick patty. Sprinkle patties evenly with salt and pepper. Add patties to pan; cook 3 minutes on each side or until done.

3) Spread about 1 teaspoon mustard blend over 4 bread slices; layer each slice with 2 tablespoons cheese, 1 patty, 2 onion slices, and 2 tablespoons cheese. Spread about 1 teaspoon mustard blend over remaining bread slices; place, mustard side down, on top of sandwiches.

4) Heat pan over medium heat. Coat pan with cooking spray. Add sandwiches to pan. Place a cast-iron or other heavy skillet on top of sandwiches; press gently to flatten. Cook 3 minutes on each side or until bread is toasted (leave cast-iron skillet on sandwiches while they cook).
