Enchilada's

My mom used to always make this recipe when I was a kid. Now I make it for my baby and he loves it.

Ingredients
1/2 Red or Sweet onion
4 Cups sour cream
1 can olives, chopped (more or less to taste)
2 cups cheese plus more for topping. I sometimes make them cheesier and add and extra cup of cheese.
Enchilada Sauce (I use Hatches brand, mild)
8-10 Tortillas

Directions
Preheat the oven to 375.
Saute onions in skillet until cooked, I like them almost caramelized so cook them longer or shorter to your taste. Mix sour cream, olives, cheese and onions together in a bowl. At this point if you want to make chicken enchilada's you would add chicken to the mix as well. I usually just make cheese enchilada's.
Get a 9x13 baking dish and put a small amount of enchilada sauce in the bottom. Fill tortilla's with the mixture, fold and place in baking dish. Cover them with remaining sauce and top with cheese (as much as you like)

Cover the dish with tin foil and bake for 20 minutes. Take the foil off and if the cheese is not melted on the top bake for another 10 minutes uncovered.
