Preheat oven to 350 F.
In a mixing bowl, mash together the refried beans and green chilies. Mix in about 1 1/4 cup of the shredded cheese in with the beans. Spoon the bean mixture evenly into the 12 corn tortillas. Roll the enchiladas and place them seam side down in a 9x13-inch baking dish. Repeat until bean mixture and tortillas are used up.
Pour the enchilada sauce over the top. Then top with the remaining shredded cheese.
Bake in the preheated oven for 20 to 25 minutes, or until cheese has melted on top.
To Freeze: Freeze before baking and cover the baking dish with foil.
To Thaw: Let thaw in the fridge overnight.
To Reheat: If cooking from partially thawed, add 15-20 minutes to the baking time and bake covered for 20 minutes, then uncovered until heated through.
