Ingredients

  • Chicken: in this recipe, I cut the chicken breasts into thin strips so they cook evenly. Chicken breasts are a great lean protein source that's also low in fat and calories.
  • Bell peppers: Using any color, slice the peppers into thin strips, removing the seeds and stem. Bell peppers are packed with vitamins and minerals, including vitamin C and potassium.
  • Onion: I used a yellow onion, but red onions would also work great! Onions add flavor and texture to the fajitas and are also a good source of fiber and vitamin C.
  • Olive oil: The olive oil will help the chicken and veggies cook and prevent sticking. 
  • Low-sodium taco seasoning: This spice blend adds a delicious Mexican-inspired flavor to the fajitas without the added sodium. Taco seasoning typically contains a lot of salt, so using a low-sodium version can help keep this dish healthy.
  • Optional toppings: Tortillas, chips, or lettuce wraps make great options for the base. Chopped cilantro, diced tomatoes, sliced avocado, shredded cheese, sour cream, and lime wedges can all be used to customize your fajitas. Choose toppings that are low in calories and high in nutrients to keep this dish healthy and delicious.
