4 boneless chicken breasts, cooked and shredded (I cooked mine in the crackpot for about 5 hours)
3 large cloves of garlic, minced
1 Jalapeno, seeded, minced
2 Tbsp butter
2 Tbsp all-purpose flour
2 cups chicken broth
2 cups sour cream (I used reduced-fat and it was still insanely good)
16 oz jar Medium Salsa Verde
1 & 1/2 tsp cumin
1/4 tsp cayenne
1/2 tsp salt
1/4 tsp white pepper
1/2 tsp garlic powder
1/4 cup cilantro, chopped
12 flour tortillas, small fajita size
1 cup shredded sharp cheddar
1 cup shredded Monterrey Jack
1/2 medium onion, diced

Preheat the oven to 350. Melt butter over medium-high heat. Saute onions and Jalapenos until soft and then add the garlic, cooking for 1 minute. Stir in the flour and let cook 1-2 minutes. Whisk in the chicken broth until smooth and let cook until bubbly. Stir in the sour cream, salsa, cumin, cayenne, salt, pepper, garlic powder and cilantro until the sauce is smooth. Remove from heat.

Spray/grease a 9×13 baking dish. Add 1 cup of sauce to the bottom of the pan. Add chicken and cheese to the center of each tortilla and roll, placing seam-side down in the dish. Pour the sauce over the enchiladas, top with leftover cheese, and bake at 350 for 25 minutes or until top is brown and bubbling.

Yields: 12-15 enchiladas
