Ingredient Notes

• Boneless skinless chicken breasts: We suggest using chicken breasts for this recipe. Thighs could work as well, but you’ll need to cook them for longer. No matter what cut you use, be sure that you use skinless chicken.
• Bell peppers: Any color of bell peppers will work for this recipe! Feel free to use one color or multiple colors, depending on what your family likes or what is on sale. Cut these into thin strips that will be easy to eat.
• Red onion: Cut your onion in half and then into thin slices. Red onion works best for flavor and color, but you could also use white or yellow.
• Lime juice: Fresh limes are best, and you’ll need about two for this recipe. Bottled lime juice will also work.
• Flour tortillas: Go ahead and use your family’s favorite flour tortillas, but we suggest warming them up beforehand.
• Toppings: We love to put a dollop of sour cream on top, and even some extra lime wedges to squeeze on top for a little extra zesty kick!

Spice Mix

While you can often find pre-made fajita spice mix in grocery stores, we recommend making your own! Each brand differs in its ratios and quality of spices in fajita spice mixes, so using our spice mix will ensure quality flavor. It only takes a few extra minutes and really enhances the flavor of your fajitas.

Red pepper flakes: Another pro of making your own spice mix is that you can control the spice level—if your family isn’t as spice tolerant, you can reduce the amount of red pepper flakes you add in. Or, if you’re really looking for some heat, feel free to add more!

How to Warm Tortillas

The typical choice is to use fajita tortillas, which are 6-inch flour tortillas, as they are the perfect size for holding all those delicious fillings. They are also typically warmed up for serving.

To warm tortillas on the stovetop: Heat a dry skillet over medium-high heat and warm each tortilla for about 30 seconds per side until soft and lightly charred.

To warm tortillas in the microwave: Stack tortillas between damp paper towels and microwave in 20-second increments until warmed through.

To warm tortillas in the oven: Wrap a stack of tortillas in aluminum foil and heat in a 350°F oven for 10-15 minutes.
