1/2 C chopped onion
1/3C lime juice (fresh squeezed if you can and add the zest from the limes)
6 cloves of garlic, coarsely chopped
1 tsp oregano
1 tsp ground cumin
1/2 tsp dried thyme
1/4 tsp ground red pepper
6 boneless chicken breasts (I used thighs)
3 tbsp chopped fresh cilantro
Combine onion, lime juice, zest, and garlic in food processor. Blend until minced.
Put in ziploc bad. Add spices (except cilantro). Add chicken, turn to coat. Marinate for 30 minutes to 4 hours (the longer the better).
Grill 5-7 minutes on each side. (I put them in the oven at 450 for 20 minutes-we were out of charcoal).
Sprinkle with cilantro and serve with favorite sides.
