In a blender or food processor, add all of the ingredients, except the chicken. Process until smooth. Pour into a zip-top plastic bag. Add chicken, seal, and massage to make sure chicken is well coated. Place in fridge for 1 hour.
Heat grill to medium high heat.
Pace chicken on the grill (discard the marinade), and grill for 5-7 minutes per side or until done. Remove from the grill and serve with Pineapple Salsa
