Chicken Enchiladas

1. Preheat oven to 350 degrees. Lightly grease a large baking dish. 2. In a medium saucepan over medium heat, melt the butter and saute the green onion until tender (about 3 to 4 minutes). Add the garlic powder, then stir in the green chiles, cream of mushroom soup and sour cream. Mix well. Reserve 3/4 of this sauce and set aside. To the remaining 1/4 of the sauce in the saucepan, add the chicken and 1/2 c of shredded Cheddar cheese. Stir together. 3. Fill each flour tortilla with the chicken mixture and roll up. Place seam side down in the prepared baking dish. 4. In a small bowl combine the reserved 3/4 of the sauce with the milk. Spoon this mixture over the rolled tortillas and top with remaining 1/2 c of shredded Cheddar cheese. Bake in the preheated oven for 30 to 35 minutes, or until cheese is bubbly.
