Chicken Marinade

I wanted to jazz up our chicken that we took to the BBQ. I did a quick search on the internet and came up with the recipe below. The recipe calls for the chicken to marinade over night, but I don't know if that would be a wise decision. I marinaded our for about two hours and our chicken had a great flavor. Leaving it in it overnight might be overpowering.

Chicken Marinade

1/4 cup cider vinegar

3 tablespoons whole grain mustard

3 cloves garlic, minced

1 lime juiced

1/2 half lemon juiced

1/2 cup brown sugar

1 1/2 teaspoon salt

6 tablespoons olive oil ( I am a moron... as I type this in I realize that I forgot the olive oil. I'll add it in next time)

ground black pepper

6 chicken breasts

1. In a large, non-reactive container, whisk together ingredients beginning with the cider vinegar though salt.
2. Then whisk in olive oil and pepper .
3. Place chicken in the mix.
4. Cover and marinade chicken in fridge for 8 hours or over night. (again, I only marinaded mine for about 2 hours and it tasted perfect. Of course adding in the olive oil will dilute the mixture, so it might need a few more hours)
5. Discard marinade
6. Either grill or bake your chicken breasts
