I used to think I made the best spicy chicken fajitas using my favorite gluten-free package mix, but then I found this recipe in the Taste Of Home Magazine. Needless to say, I won’t be buying that package mix anymore.


Different colored peppers and onions are colorful, healthy, and the perfect combination with marinated chicken or steak.

Why Do I Love This Recipe?

  • It only needs to marinate for 30 minutes.
  • Leftovers are as good as the day you made them.
  • My family loves it.
  • Allergy-friendly plus it’s a healthy recipe.
  • It’s a perfect meal for any day of the week.

Beef fajitas are drool-worthy too. Sirloin steaks cut into strips are amazing in this marinade.

These easy chicken fajitas are perfect for:

  • wraps
  • bowls
  • salads ~ Southwestern salads are one of our favorite meals. Add chopped romaine lettuce to a bowl topped with chicken, sliced red onion, olives, corn, black beans, avocado, and salsa. I always add some crunched-up chips too.

There are many different varieties and brands of gluten-free tortillas; sometimes, choosing which one to buy is hard!  My favorite gluten-free tortillas are Mission Gluten-Free Tortillas. I buy both the regular and Spinach Herb. Sometimes I even use these tortillas for a gluten-free pizza.
