Black Bean Rice Burgers

Black Bean Rice Burgers-shared by Taste of Home
-we did like this recipe...but i was having trouble keeping them together. K was surprised at how good they were and they were made tasty by the sauce. I did add shredded cheese to the top to help keep them together.

• 
  1 can (15 ounces) black beans, rinsed and drained
• 1 cup cooked brown rice
• 1 small onion, finely chopped
• 1 egg, lightly beaten
• 2 tablespoons plus 1/4 cup salsa, divided
• 1/4 cup reduced-fat sour cream
• 4 lettuce leaves
• 4 slices reduced-fat cheddar cheese (1 ounce each)
• 4 hamburger buns, split
  
  In a large bowl, mash beans with a fork. Add the rice, onion, egg and 2 tablespoons salsa; mix well. Drop by 1/2 cupfuls into a large nonstick skillet coated with cooking spray. Flatten to 1/2-in. thickness. Cook over medium heat for 4-5 minutes on each side or until firm and browned.
  In a small bowl, combine sour cream and remaining salsa. Place a lettuce leaf, burger, sour cream mixture and slice of cheese on bun. Yield: 4 servings.

• Kids Help: dump, rinse/drain beans, help mash beans, mix ingredients.
  
  
  Next Time: I will use a real egg vs. a substitute, this could have been the cause of why they didn't stick together. I will also make them thicker as that may help as well.
