Cherry-Stuffed Grilled Chicken

The weather's been quite nice around here and I thought of getting one more use out of our grill. :)  Good thing, because I just made this last night, then we woke up to snow this morning!  Crazy weather!  Anyway, this recipe is simple and great because you can use frozen cherries instead of fresh ones and still get that nice sweetness.  The flavors are not overpowering, but they do blend quite nicely.  Enjoy!
-3/4 cup fresh or frozen cherries, pitted (and thawed, if frozen)
-2 Tbs chopped onion
-1/2 tsp rubbed sage (found in the spices isle)
-1/2 tsp salt
-1/2 tsp dried thyme leaves
-2 chicken breasts, skinless, boneless
-3 Tbs extra virgin olive oil
-2 Tbs white wine vinegar
-1 tsp garlic powder
-1/2 tsp salt
-1/2 tsp pepper
Roughly chop the cherries and combine with onion, sage, salt, and thyme.  Mix well.
Cut a pocket on the thicker side of each chicken breast.  Season lightly with some salt on both sides.  Stuff each pocket with the cherry mixture.  Close opening with toothpicks.  Place chicken in nonreactive pan.
In a small bowl, mix the rest of the ingredients. Mix very well, and pour over chicken.  Cover and refrigerate for 30 minutes.
Remove chicken from marinade and grill until cooked through.  Enjoy!
