Unbelievable Chicken!!!

Ok, The way I will do this is post at least one "Challenge" at the beginning of every week for you to make before the next Challenge. So for this week, I've chosen a VERY popular recipe I found online that is what I call, "The Fool-Proof-Recipe for Grilling Chicken Breasts"! It turned out great my first try!
SO:

Ingredients:

1/4 cup cider vinegar                                      1/2 cup brown sugar
3 Tbsp prepared coarse-ground mustard         1 1/2 tsp salt
1 lime (juiced)                                             Ground black pepper to taste
1/2 lemon juiced                                             6 Tbsp olive oil
3 cloves garlic (peeled and minced - I buy the already minced garlic in a jar at the grocery store)
6 skinless, boneless chicken breast halves (thicker the better in this case)

Directions:

1. In a large bowl: mix the cider vinegar, mustard, garlic, lime juice, lemon juice, brown sugar, salt, pepper. Whisk in the olive oil until everything is mixed well. (Now I usually do this in a large plastic mixing bowl for which I'll explain later). Place chicken in the mixture. (I do this one at a time and make sure each piece is soaked thoroughly and just leave them in the bowl) because you then cover it and place in the fridge to let it marinate for 8 - 12 hours overnight....I highly recommend 12. I recommended the plastic bowl since it's cheaper and easy to clean! 
2. Once marinaded, preheat outdoor grill, I've been told indoor is fine as well. Make sure grate is slightly oiled so the chicken wont stick.
3. Place chicken on the prepared  medium-high heated grill and cook 4 - 7 min per side, depending on thickness of chicken to get tender results and you see the juices running clear. If grill is on HIGH, turn it down or the chicken will burn to the grate from the marinade so make sure it's closer to medium-high. (I know from experience).  

And it's that simple! I have cooked up to 50 of these at one time for a Christmas Party event and it turned out great as well as a simple dinner with the family! This is a tough one to mess up to the point you can't eat it, but if you do need a "Redo", please don't give up because I promise that once you get this down, it will be in your top two  BEST recipes for chicken!!! Please let me know how it turns out!
