One large onion (about one cup chopped), 6 garlic cloves (peeled), 3 Tablespoons good Olive Oil, 1 teaspoon kosher salt, 1 teaspoon black pepper, 1 cup fresh lemon juice. This is enough to marinate 10 large chicken breasts.
Blend all ingredients in food processor or blender until rather smooth. Marinate skinned chicken in single layer with mixture covering all the meat for 30 minutes. Mixture will be thick and will coat the chicken heavily. Grill chicken until done through and nicely browned. Discard remaining marinade. Allow chicken to rest for a few minutes before serving.
This receipe is simple and so very yummy. I grill up a large amount of chicken breasts and freeze them to enjoy all month long.
