I found this recipe on allrecipes submitted by Kimm. I have made several changes to it. If you want a mild spice go with mild enchilada sauce. I use 1/2 mild and 1/2 hot as we like things spicy. The kids request this often!
In a bowl combine sour cream, onion, totatoes, refried beans, garlic and 3/4 of the cheese.
Into a 9x13 pan pour a small amount of enchilada sauce to coat bottom of pan. Layer 6 tortillas on bottom of pan. Layer half of the cheese-sour cream mixture over the tortillas. Repeat this layer once more. Pour the remaining enchilada sauce over the final layer of tortillas. I ususally top with a sprinkle of cheese.
Bake 20 - 30 minutes. Cut into squares and serve. I serve with salad and crusty bread.
