If chicken breast is thick, cut in half, long ways, to make it thinner (it will cook quicker).
Add all ingredients except chicken into a zip-lock bag. Mix well. Add chicken to bag and make sure it is thoroughly coated. Let marinate for at least 4 hours or overnight.
Grill chicken over medium-high heat for 6-8 minutes each side (or until the chicken is no longer pink in the middle).
While the chicken is cooking, pour the marinade into a sauce pan. Cook over medium heat and simmer for about 10 minutes. The marinade should thicken.
When chicken is done, top with the marinade sauce, cilantro, and a lime wedge on the side.
