Spread your mixture into a deep roasting pan that has been buttered or greased. Add in a layer of cheese. Add in your taco mixture, making sure there is plenty of liquid. This liquid is needed to steam the tamale from the inside. Finally, add a last layer of cheese and cover with the remaining tamale dough. If it has thickened too much, add a little water to loosen it and make it spreadable. Top with more cheese and bake at 350°F for an hour.
