Preheat oven to 350 F. Using fingers, loosen skin on chicken legs. Spoon some filling into each chicken leg working the stuffing down the drumstick. Combine the 2 Tbsp melted butter, dry mustard & Dijon mustard together & brush over chicken. Place the chicken in a shallow baking dish & bake for about 45 minutes or until cooked through. Remove from oven & serve.
