Preheat oven to 350° F. Spray 24 mini muffin cups with non stick cooking spray. Separate dough into 4 rectangles; pinch perforations to seal. Cut each rectangle into 6 squares. Press each square in bottom and up side of mini muffin cup. Bake 6 minutes. Remove from oven. Using handle of wooden spoon, immediately make 1 1/2 –inch indentation in center of each cup.
Meanwhile sauté the onions in 1 tsp of oil until tender, then combine the meatballs, bbq sauce and 1 tbsp. of water in the skillet over medium heat. Cook and stir until heated through, about 3 to 4 minutes. Place each half of the meatballs into the crescent cups, cut side facing up. Top each cup with a slice of cheese. Bake for an additional 8 to 10 minutes longer or until edges are golden brown. Cool 1 minute, then remove cups.
While they are finishing baking, render bacon pieces in a skillet until crisp. Drain on a paper towel lined plate. Top each cheeseburger bite with a piece of bacon and serve warm. Enjoy!
