When I had my most recent baby, a friend brought us this dinner. I had to get this recipe! I've found that it's pretty popular and have seen it shared online a few times since.
2 chicken breasts
1 cup bbq sauce
1/4 - 1/2 cup zesty Italian salad dressing
1/4 cup brown sugar
1 tbsp worcestersire sauce
Place all ingredients in the crockpot and mix together. Cook on high 3-4 hours. Shred and serve on buns.
