Cook ground beef thoroughly. While beef is cooking, put wonton wrappers in 10 muffin tins (2 per tin).
Drain beef and add to muffin tins.
Top each with 1/2 tbsp. ketchup.
Add 1 tbsp cheese to each.
Bake at 350° for 10-12 minutes, or until wonton wrappers turn a golden color.
Microwave pre-cooked bacon or cook 4 slices regular bacon and divide into 10 pieces (you may have a little left over...it makes a nice snack).
When wontons have finished baking, top with bacon, pickle, lettuce and tomato. Serve hot and enjoy!
