Chicken Enchiladas with Creamy Green Chile Sauce

Why I Love This Recipe
One of the ladies in my Bible Study group made these for a dinner party and they were the best. She has told me that she adapted it from a recipe on from Campbells. I did a little research and found the closest I could. Enjoy!!
Ingredients You'll Need
1 can (10 3/4 ounces) Campbell's® Condensed Cream of Chicken Soup (Regular or 98% Fat Free)
1/2 cup sour cream
1 tablespoon butter
1 medium onion, chopped (about 1/2 cup)
1 teaspoon chili powder
2 cups chopped cooked chicken or turkey
1 can (about 4 ounces) chopped green chiles
8 flour tortillas (8-inch), warmed
1 cup shredded Cheddar cheese
OR Monterey Jack cheese (about 4 ounces)
Directions
Stir the soup and sour cream in a small bowl.
Heat the butter in a 3-quart saucepan over medium heat. Add the onion and chili powder and cook until the onion is tender.
Stir in the chicken, chiles and 2 tablespoons soup mixture.
Spread 1/2 cup soup mixture in a 2-quart shallow baking dish.
Spoon about 1/4 cup chicken mixture down the center of each tortilla. Roll up and place seam-side down into the baking dish.
Spoon the remaining soup mixture over the tortillas.
Sprinkle with the cheese.
Bake at 350°F. for 25 minutes or until the enchiladas are hot and bubbling.
Tip: You can substitute 3 cans (4.5 ounces each) Swanson® Premium White Chunk Chicken Breast in Water, drained, for the chopped cooked chicken.
