Sour Cream Enchiladas

I got this recipe from coolestmommy

1 to 1.5 lb. ground beef
1 pkg. 10 inch flour tortillas
1 pkg. taco seasoning mix
1 small can chopped green chilies
1 small can evaporated milk
1 (8 oz) sour cream
1 can cream of mushroom soup
5 oz. grated cheddar cheese

Brown ground beef and drain off fat. Mix in taco seasoning and green chilies. Add 1/2 cup water and simmer for 15 minutes. Mix canned milk, sour cream and soup in another pan. Cook over low heat until boiling and thick. Put 2 tablespoons meat mixture on each tortilla and roll up. Pour sauce over enchiladas and cover with cheese. Place in oven at 350 until cheese melts.
