Mix the corn muffin mix, milk, and egg until a smooth consistency is formed and set aside.
In a large skillet brown the meat and add the taco seasoning as instructed on the packet.
In a medium skillet warm the beans and corn, then add in the cooked and seasoned ground beef. Let this simmer for 5 minutes. Pour this mixture into a 9inch pie pan and spread the corn muffin mixture on top.
This will bake in the oven for 15 minutes or until the corn muffin mix is completely done.
