Make mashed potatoes, either by boiling the potatoes and mashing with butter and milk, or use instant potatoes. Take a square of foil, and place a damp paper towel on it. Fold in a square, so the paper towel is covered up. This will keep the bottom from burning the food.
Place this square in the middle of a large square of foil, that is laying flat. Next, on top of the small square of foil-covered paper towel, plop a mound of mashed potatoes. Add cheese (we like sharp cheddar), and bacon pieces. Fold up like a Hershey Kiss, and place on hot coals for for 15-20 minutes. Open packet and eat!
