Combine ingredients from lime zest to salt and pepper in a large bowl or ziplock bag then mix well. Add chicken breasts then cover and marinate in the refrigerator for 1-4 hours.
When ready to grill or cook, let chicken breasts rest out of the fridge for 10-15 minutes then grill or saute over medium-high heat for 4-5 minutes a side, or until cooked through. Serve with Cilantro-Lime Rice and Guacamole.
