  • 8 (6 inch) corn tostadas


  • Spray slow cooker with non-stick cooking spray and place chicken breasts inside. Top with salsa and fajita seasoning.
  • Cook on low for 5-6 hours or 2-3 hours on high.
  • Remove the chicken breasts and shred the chicken with two forks. Return the shredded chicken to the slow cooker, along with the sliced peppers and onion. Cook on high for 30 minutes or until the peppers are tender.

To turn this into a freezer meal:
Add chicken, salsa, and seasoning to a gallon-sized freezer bag. Squeeze out as much air as possible and seal bag closed. Place freezer bag into freezer and it will last 60-90 days. When ready to use, spray inside of slow cooker with non-stick cooking spray and dump ingredients from bag into slow cooker. Add 15 ounces of chicken broth in with the frozen food. Place the lid on top. Cover and cook on LOW heat for 6-8 hours (or HIGH heat for 3-4 hours - every slow cooker will cook a little bit differently). Follow the rest of the instructions as written.
