Chicken in Mustard and Vinegar

4 tablespoons white wine vinegar
1.5 tablespoon wholegrain mustard

4 tablespoons olive oil

1 tablespoon bbq sauce

4 chicken breasts

1 tablespoon olive oil (for frying)

Mix the vinegar, mustard, oil and bbq sauce in a wide bowl. Add the chicken breasts. Then let the chicken marinade for 4 hours plus. Turn the chicken pieces at least once.

Heat a large skillet, add the oil and cook the chicken breasts. Turn half way through. When the chicken breasts have cooked through add the marinade and cook for 4 minutes.
