Place the breasts of chicken between two layers parchment/baking papers and flatten slightly with a meat mallet/rollingpin.
Mix together all the marinade ingredients.
Pour the marinade over the chicken and place it in a glass container. Mix well and cover the chicken. Let it marinade for at most 20 minutes, but up to 24 hours.
Cook the breasts of chicken in a skillet or pan. Once the chicken is cooked, place the chicken on the grill and cook for about 3-5 minutes (depending upon the thickness).
Cover the chicken with foil and remove from heat. Let it rest for 5-10 minutes before you serve.
