Place 1 tablespoon of olive oil in a large pan or dutch oven that has a lid and sauté onions and garlic until translucent and aromatic. In the mean time, place your chicken tenderloins in a bowl or plastic bag and add 1 tablespoon of olive oil, taco seasoning (or make your own homemade
taco seasoning) and shake or stir to coat the chicken with the marinade. By this time, your onions should be cooked perfectly. Sprinkle with a little of fresh lime juice. Keep warm.
