Melt butter and pour into a large mixing bowl. Mix in the worchestershire, sea salt, chili powder, garlic powder and onion powder. Once fully combined toss the remaining ingredients into the butter and mix well.
Spread evenly between two baking sheets and bake on the middle rack for 1 hour. Stir the Christmas Chex Mix every 10/15 minutes to ensure even baking.
Cool to room temperature before packing into air tight containers.
