Spoon 1/2 cup of the pork into each pepper half and sprinkle with cheese.
Spray 6 sheets of tin foil with non-stick spray (this helps the cheese not to stick!) and place a pepper half in the middle of each sheet. Fold up the sides of the tin foil to seal.
*To make ahead, place in the refrigerator up to 24 hours in advance.
Preheat the grill to roughly 450 degrees F. Reduce heat on one side of the grill and place your tin foil wrapped peppers on the side with lower heat. Grill for 10-15 minutes and then open to check doneness. If desired, remove from tin foil and grill on the hotter side of the grill for 2-3 minutes to char the peppers.
*Slow Cooker: place tin foil wrapper peppers in the slow cooker and cook on low for 2 hours (cooking time will vary based on slow cooker model) *Oven: place on a baking sheet and bake at 400 degrees F for 20-25 minutes or until they reach desired doneness.
