Chicken with Tomatoes and Olives

Preheat grill to medium-high or oven to 450 degrees F.

Center one chicken breast half on each sheet of Reynolds™ Wrap Everday Heavy Duty aluminum foil.  Top with onion.  Combine tomatoes and olives; spoon over top.

Bring up foil sides.  Double-fold top and ends to seal packet, leaving room for heat circulation inside.  Repeat to make four packets.

Grill 14 to 18 minutes in covered grill OR bake 20 to 25 minutes on a cookie sheet in oven.

Serve over spaghetti; sprinkle with cheese.
