Open a 1 gallon Ziploc bag and set on your work area or use a large mixing bowl
Slice 1 large head of garlic, chop 1 yellow or sweet onion, chop 1 jalapeno (remove seeds and white meat of the jalapeno for no heat)
Add garlic, onion, and jalapeno to the Ziploc bag or mixing bowl
Juice 2 large limes and 2 oranges, add the juice to the marinade
Add to the marinade 1/3 cup olive oil, 1 Tbsp apple cider vinegar, and all of the marinade seasonings: 2 Tbsp of chili powder, 1 Tbsp Paprika, 1 Tbsp Oregano, 1 Tbsp crushed red peppers, 2 tsp cumin, 1 1/2 tsp salt, 1 tsp granulated garlic, 1 tsp granulated onion, 1 tsp chicken bouillon, and 1/2 tsp black pepper
Zip the Ziploc bag closed and shake the ingredients together or stir the ingredients in a large mixing bowl
Add boneless skinless chicken thighs to the marinade, zip the bag closed, and squeeze the bag pushing the marinade around the chicken thighs evenly
*or stir marinade with the chicken thighs in a bowl using a large cooking spoon, tongs, or your hands and cover with plastic wrap
*I use chicken thighs because the meat is always juicy, tender, and has a rich flavor
Let the marinating chicken sit in the refrigerator for at least 4 hours and up to 12 hours
