Place chicken on a baking sheet in a single layer. Stir cream cheese in a mixing bowl until nice and smooth. Then add ranch dressingBBQ sauce, and cheddar cheese. Place in a baking dish (not the one you're planning on serving it in) and place in the oven along with the chicken. Bake 8 minutes at 425*, flip chicken, then bake 8-9 more minutes. Remove both dishes from the oven.
Carefully place dip back in the same mixing bowl as before and add chicken stir together and place in the baking dish used before. Heat 5-10 more minutesor until heated all the way through. Top with green onions and serve with crackers.
