I found this recipe on "www.myrecipes.com". A quick five-ingredient sauce tops cheesy homemade burgers to make an easy, delicious dinner in no time.
1 tsp olive oil
4 cups vertically sliced red onion
4 tsp sugar
4 tsp red wine vinegar
3/4 tsp chopped fresh thyme
3/4 tsp chopped fresh oregano
1/2 tsp salt
1/4 tsp garlic powder
1 lb extra lean ground round
4 (1/2 oz) slices white cheddar cheese
4 ( 1 1/2 oz) hamburger buns, toasted
4 tsp canola mayonnaise
Prepare grill to medium-high heat.
To prepare jam, heat a large nonstick skillet over medium-high heat. Add oil to pan; swirl to coat. Add onion; saute 5 minutes. Reduce heat to medium-low; stir in sugar, vinegar, and thyme. Cover and cook 10 minutes or until onion is very tender. Remove from heat.
To prepare burgers, combine oregano, salt, garlic powder, and beef. Divide mixture into 4 equal portions, shaping each into a 1/2" thick patty. Place on grill rack coated with cooking spray; cook 2 minutes. Turn patties over. Place 1 cheese slice on each patty; cook 2 minutes or until done.
Spread cut sides on each bun with 1/2 tsp mayonnaise. Place 1 patty on bottom half of each bun; top each with 1/4 cup onion jam and bun top.
