Chicken Enchiladas

I had searched forever to find a good enchilada recipe without a green or red sauce...and I finally found it!

Ingredients:
2 little cans chopped chopped chicken
2 cans cream of chicken soup
1 little can chopped green chilies (optional)
2 chopped green onions
1 pint sour cream (I just use 2 cups/16 oz. plain yogurt instead)
10-12 medium flour tortillas
Grated yellow cheese

Directions:
1. Saute onion in butter in a deep pot.
2. Add cream of chicken soup, chicken, and chilies. Stir until just mixed and beginning to warm. Turn off heat and add sour cream (or yogurt). (At this point, I also add a few spices--garlic, seasoning salt, etc...just whatever I feel)
3. Place 2 tortillas in microwave at a time and heat to soften and warm. Place about a 1/4 cup of the mixture in the middle of tortilla and then wrap up and place in a 9x13 pan with seam down. pour rest of mixture on top and spread so none of the tortillas are dry. Place LOTS of grated cheese on top.
4. Cover with foil and back at 350 for 20-30 minutes or until bubby.
