  • 4 chicken breasts about 1 lb total
  • 2 tbsp olive oil
  • 1 tbsp apple cider vinegar
  • 1 tsp paprika
  • ½ tsp salt
  • ½ tsp ground cumin
  • ½ tsp dried thyme
  • ¼ tsp onion powder
  • 1 avocado peeled and sliced
  • 2-4 slices pepper jack cheese depending on how cheesy you like it
  • Optional: bread to make into a grilled sandwich


Prepare Chicken:

  • Combine olive oil, vinegar, salt, paprika, cumin, thyme, and onion powder in a Ziploc bag or Tupperware container. Place thinly cut chicken breasts in container with marinade and toss well to coat each breast. Allow chicken to marinate in the fridge for at least 4 hours or overnight.

To Bake:

  • Preheat oven to 350F. Meanwhile, place cast iron skillet on stove and heat on high. Once smoking, add chicken breasts.
  • Cook 1 minute on each side, or until lightly browned. Transfer skillet to the preheated oven and cook 10 minutes, or until cooked through.
  • Remove pan from oven and immediately top each breast with slice of cheese. Plate each breast and top with avocado slices. Enjoy!

To Grill:

  • Heat grill on medium-high heat. Place chicken on grill and cook about 5 minutes/side or until cooked through. Before removing from grill, place 1 slice of cheese over chicken and allow to cook another minute until cheese is starting to melt.
  • Remove chicken from grill and top with sliced avocado.


These also make for a great grilled chicken sandwich, simply place between two slices of grilled or toasted bread. See instructions in post.
