Preheat oven to 400 degrees F. Soak toothpicks in water to prevent them from burning in the oven.
In a large bowl, mix chicken with melted butter and hot sauce until well coated. Lay a 1/2 slice of bacon flat and fill with one piece of chicken, and one piece of blue cheese in the center. Fold the bacon over the filling and use a toothpick to close tight.
Cook in the oven until the bacon is crisp and sizzling, about 25 minutes.
