Grilled BBQ Chicken

My husband found this recipe in a magazine over at his dad's house, and we've had it quite a few times.  It tastes so good right off the grill!

Chicken breasts (3-4 breast halves)
2 tbsp. Orange marmalade
¼ c. BBQ sauce
¼ c. Italian dressing
¼- ½ c. Italian dressing (for marinade)

Marinate chicken breasts in ¼- ½ c. Italian dressing for 1-24 hours. Combine BBQ sauce, Italian dressing, orange marmalade into glaze. Cook chicken on grill until no longer pink in center. Before taking chicken off grill, glaze with mixture and cook for about 2-3 more minutes.
