  • 1 cup Cheez-Its crumbed
  • 2 Tablespoons taco seasoning mix
  • 4 large boneless skinless chicken breasts or 8 small
  • 4 green onions chopped
  • 2 Tablespoons butter
  • 2 cups fat-free half & half
  • 1 cup Pepper Jack shredded
  • 1 cup sharp cheddar cheese shredded
  • 1 can 4 oz chopped green chiles, do not drain


  1. Preheat oven to 350 degrees. Prepare a 13x9x2-inch baking dish by spraying with a non-stick spray.
  2. Crumb Cheez-Its by placing into large ziploc bag and seal. Using a rolling pin, just roll over it in different directions until there are only fine crumbs left. You can also save time by grinding it in a small chopper. I like the Ninja Chopper, works well and easy to clean.
  3. Mix crumbed mixture with the taco seasoning in the same bag.
  4. Place the chicken pieces, one at a time, in the bag and shake to coat.
  5. Place chicken into prepared pan in a single layer. I like to pat the remaining seasoned crumbs left in the bag onto the chicken.
  6. In a medium skillet, melt butter and sauté green onions until tender.
  7. Stir in half & half, cheeses and green chiles.
  8. Pour over chicken then place in oven, uncovered, and bake for 45 minutes.
