This chipotle grilled chicken with pineapple and avocado strikes the perfect balance of spicy and sweet. Enzymes in the fresh pineapple help tenderize the chicken breasts in only 15 minutes. Be sure to take them out of the marinade after the 15 minutes is up to prevent the meat from breaking down. To save time, you can use pre-cut pineapple.
