First, peel and begin boiling your potatoes. While potatoes are boiling cook your ground chuck. Set ground chuck aside for later. Next drain potatoes and mash using a hand blender. Set these aside as well.
Put the Velveeta cheese in a large pan and melt fully using milk to keep consistency lower. In a large bowl mix cream corn, whole kernel corn, melted Velveeta cheese, and cooked ground chuck. Pour mixture into a large casserole dish and fully cover with mashed potatoes.
Cook at 350 degrees F for 10 to 15 minutes or until potatoes brown at edge.
