Cook/shred your chicken breast and mix it with 1 cup of shredded cheese.
Lay 8 tortillas out and fill each one with the chicken mixture making sure they are all even. Roll them up tightly and put them in a greased 9×13 baking dish.
In a saucepan, melt the butter and add in the 3 tbsp of flour. Mix and cook for about one minute.
Add in the 2 cups of chicken broth, whisking until it’s a smooth consistency. Whisk over medium heat until it is thick and creamy (usually takes about 5-8 minutes).
Mix in the sour cream, salt/pepper, and the can of chiles to the pan.
Pour the creamy sauce over the rolled up tortillas evenly.
Add 1 cup of the cheddar cheese over the top.
Bake for 20-25 minutes or until the cheese is golden brown. Add salsa or cilantro and you’re ready to eat!
