My Favorite Burger Recipe

In a large bowl, combine the onion, garlic powder, salt and pepper. Crumble beef over mixture and mix well. Shape into four patties. Using long-handled tongs, moisten a paper towel with cooking oil and lightly coat the grill rack. Grill, covered, over medium heat or broil 4 in. from the heat for 4-6 minutes on each side or until a meat thermometer reads 160°. Meanwhile, in a small skillet coated with cooking spray, cook and stir mushrooms and onion over medium heat until onion is golden brown. Grill rolls for 1-2 minutes or until lightly toasted. Spread rolls with cream cheese; top with burgers and mushroom mixture. Sprinkle with bacon.
