If memory serves me correctly (and there are no promises there) I think Charlie first posted this incredible marinade


Unbelievable Chicken Marinade

1/4 cup cider vinegar
1.5 T. whole grain mustard
1.5 T. Dijon mustard
3 cloves garlic, peeled and minced
1 lime, juiced
1/2 cup brown sugar
1.5 tsp. salt
6 T. olive oil
ground pepper to taste

Boneless, skinless chicken breast halves

In a large, non-reactive container, thoroughly mix all ingredients up to salt. Whisk in olive oil and pepper. Place chicken in the mixture. Cover, and marinate chicken in the refrigerator 8 hours or overnight.

Preheat an outdoor grill for high heat, and lightly oil grate. Place chicken on the grill (pour leftover marinade into pan and boil several minutes. Then it can be served alongside the chicken.) and cook until desired doneness.
