Mix in a small bowl using a wire whisk:
1 c of olive oil
4 cloves of garlic, peeled and chopped
¼ c purple onion, peeled and chopped
¼ tsp. ground cilantro or 1 T of freshly chopped cilantro
¼ tsp. cumin
¼ tsp. rosemary or 1 T fresh, chopped
This is easy-peasy to whisk together in a jiffy, is made from fresh ingredients, and contains no toxic chemical ingredients like the manufactured bottled versions. Pour over skinless boneless chicken breasts and refrigerate overnight. The next day, remove the chicken from the marinade and bake in the oven or toss it on the grill.
