In a small bow or marinating jar, combine the apple cider, mustard, vinegar, olive oil, garlic, coconut aminos, honey, and season with salt and pepper to taste.
Place the chicken in a marinating container and pour the marinade on top.
Place the chicken in the refrigerator and marinate for 4 to 8 hours.
Preheat your oven to 400 F.
Pour the marinade into a small saucepan and bring to a boil; then lower the heat and let simmer for 10 to 15 minutes.
Spread the chicken in a baking dish, and cook in the oven for 20 to 25 minutes, basting with the mustard marinade every 10 minutes.
