Trim the fat from each chicken breast and pound, butterfly, or slice each breast to about 1/2 inch thickness.
Place pounded chicken breasts into a gallon sized Ziplock bag.
Add 1/2 12 oz can Minute Maid Frozen Limeade Concentrate, 1 12 oz can water, 1/2 cup vegetable oil, 1 bunch of cilantro finely chopped, and the juice and rinds of 2 limes into the bag and add salt and pepper to taste.
Zip the bag securely shut and refrigerate for 3-4 hours.
Place the chicken breasts on the grill over medium heat and cook for 4-8 minutes per side, or until the juices run clear and the thickest part is no longer pink.
Serve on a bed of cilantro lime rice topped with avocado mango salsa.
