For the chicken:

Preheat oven to 350 degrees.

Spray a roasting pan or Dutch oven with cooking spray. Place chicken thighs into pan. Add jalapenos, jalapeno juice, onion, garlic, chicken broth, cumin and seasoned salt.

Braise in oven for 2 hours (the meat will be very tender and there will be a lot of juice left in the pan…about 3 cups). Remove from oven and remove chicken thighs onto a platter to cool. RESERVE 2 cups braising broth. Once chicken has cooled, shred with a fork; set aside.

For Suiza sauce:

In a deep skillet, melt butter. Add flour, stirring constantly for about 1 minute. Stir in garlic, then immediately stir in broth all at once and continue stirring until well combined and smooth. Stir in salsa verde, green chiles, and sour cream. Season with salt and pepper to taste.

Spray a deep 9x13 baking dish with cooking spray and add about 1 cup of suiza sauce into the bottom. Layer ¼ of the tortilla pieces, then shredded chicken, a little more sauce, then cheese. Continue repeating these layers. End with tortilla pieces, remaining sauce and remaining cheese.

Bake at 350 degrees for about 40 minutes, or until hot and bubbly. Let stand for 10 to 15 minutes before cutting and serving.
