Four 115 to 170 grams skinless, boneless chicken breast halves
1 cup of American Garden pizza sauce or Mushroom Pasta sauce
1 cup shredded mozzarella cheese
20 thin slices beef pepperoni
1 medium green bell pepper, seeded and chopped
1 small onion, chopped
Grated Parmesan cheese (optional)

1) Preheat the oven to 232°C or prepare a charcoal or gas grill so that the coals are medium-hot.

2) Lay four 12-by-18-inch sheets of aluminum foil on a countertop, non stick (dull) side facing up. Rinse the chicken and pat dry.
Put a chicken breast in the center of each sheet and spoon pizza sauce over each one. Sprinkle with cheese and then top with pepperoni, bell pepper, and onion.

3) Bring up the side of the foil. Double fold the top and ends to seal the packets, leaving room for heat circulation inside. Repeat to make 4 packets. If using the oven, put the packet on a cookie sheet.

4) Put the cookie sheet in the oven or slide the packets onto the grill rack. Bake for 20 to 24 minutes or grill for 12 to 14 minutes in a covered grill, or until the chicken is tender , the juices run clear, and an instant –read or meat thermometer registers 170 F. Sprinkle with grated Parmesan cheese before serving, if desired
