Amazing grilled chicken marinade recipe chicken marinated in a mixture of apple cider vinegar, dijon mustard, garlic, olive oil, lemon and lime juice, and brown sugar. Sweet and tangy in every bite It is truly amazing. We ate this two nights in a row. Everyone gobbled it up. Leftovers are great chopped up on a salad or in a sandwich wrap. Gluten-free and easily adapted to a low-carb/keto-friendly diet.
