Make chicken ahead of time for ease. 3-4 chicken breasts, seasoned with cumin, garlic powder, and pepper. Can add a little chipotle sauce for flavor.

10 flour taco shells
2-3 cups cooked, shredded chicken *see notes*
2 ½ cups shredded Monterey Jack cheese (2 blocks)
3 Tbsp butter
3 Tbsp flour
2 cups chicken broth
1 cup sour cream
1 can (4oz) diced green chilies

10 flour taco shells 2 -3 cups cooked, shredded chicken *see notes* 2 ½ cups shredded Monterey Jack cheese (2 blocks) 3 Tbsp butter 3 Tbsp flour 2 cup s chicken broth 1 cup sour cream 1 can (4oz) diced green chilies

Preheat oven to 350 degrees. Grease a 9x14 pan.
Mix shredded chicken and 1 cup of cheese in a bowl. Roll up the chicken into the 10 tortillas and place seam down in the prepared pan.
In a medium saucepan, melt the butter over medium-high heat. Stir in the flour and stir while cooking for 2 minutes.
Add in the broth and whisk until smooth. Heat over medium heat until thick and bubbly. Remove from heat for 5 min then add sour cream and chilis (so the SC won't curdle). When it is mixed well, pour your sauce over the enchiladas in the pan.
Top with the remaining cup cheese.
Bake for 20 minutes and then broil on high for 2-3 minutes at the end to get the cheese bubbly.
