In a mixing bowl mix cooked and shredded chicken breast with taco seasoning, salsa, and green chilies.
Preheat oven to 350 degrees F. Prepare a casserole dish with nonstick cooking spray then stand taco shells inside.
Spoon in refried beans to the bottom of each shell. Top with chicken and then shredded cheese. Bake for 10 minutes or until cheese is melted. Remove from oven and serve topped with your favorite taco toppings.
I used the stand and stuff taco shells for this recipe to make sure my tacos would stand nicely. You could use regular taco shells but would probably use closer to 12 taco shells instead of the 9 I used since they usually are smaller.
