Nutritious and satisfying: Balanced with protein and healthy fats to help you feel energized and satisfied.

What you need to make these fajitas using rotisserie chicken

Rotisserie chicken: Saves time while adding flavor and protein. You can also use any type of leftover chicken, just shred or dice.
Bell pepper & onion: Classic fajita veggies for plenty of nutrition, color, and crunch.
Oil: Use light olive oil or avocado oil for a healthy fat to help caramelize the vegetables.
Fajita seasoning: A quick way to add bold flavor.

How to make skillet chicken fajitas with rotisserie chicken

1. Prepare ingredients: Shred or dice your leftover chicken and slice the bell pepper and onion.

2. Cook the veggies: Heat olive oil in a large skillet over medium-high heat. Add bell pepper and onion, cooking for about 3-4 minutes until slightly softened.

3. Add the chicken. Stir in the rotisserie chicken and sprinkle with fajita seasoning. Add the amount of water listed on the seasoning packet. Cook for another 1-2 minutes, stirring occasionally, until everything is heated through.

4. Assemble the fajitas: Warm the tortillas in a dry skillet or microwave. Divide the fajita mixture among the tortillas.

5. Add toppings: Top with your favorite toppings, like shredded cheese, salsa, Greek yogurt, or avocado slices.

How to adapt this recipe for a low-energy day

Want to make this recipe but need it to be even easier? I got you! Here are some easy ways to shave down time and effort

Skip slicing veggies and use a frozen bell pepper and onion mix.
Use pre-chopped rotisserie chicken from the grocery store.
Swap tortillas for rice and turn this into a fajita bowl.
Skip the stove altogether and microwave everything in a dish before serving.

Variations or How to make this recipe your own

Make it dairy-free: Avoid cheese, sour cream, or Greek yogurt for the toppings.
Make it low-carb: Use a low-carb wrap or large lettuce leaves instead of a traditional tortilla.
Add more veggies. Make your filling more nutrient-dense and filling by sauteing diced mushrooms, zucchini or spinach with the onions and peppers.
Make it kid-friendly. You can remove the peppers and onions from the pan before adding the chicken and fajita seasoning, or add the fajita seasoning to just the peppers and onions, and serve the filling ingredients separately to make this recipe work for all ages and taste preferences. You can also use hard taco shells or tortilla chips if that’s what you’re kiddos like best!
Make it spicier: Add a dash of hot sauce or saute sliced jalapenos along with the peppers and opinions for a spicy kick.

Tips

Don’t overcook the chicken. Since you’re using pre-cooked chicken, you just want it to warm through by heating it for a minute or two.
Slice the veggies thinly and evenly so they cook quickly.
Toast your tortillas for more flavor! If you have a gas stove (I miss mine!) you can turn the heat on low and VERY briefly lay the tortillas over the top, watching closely. Or you can toast them in a pan, toaster oven, or even in the toaster!

Make ahead, freezing, and storage instructions

Make ahead and storage instructions: This filling is a good option for meal prep. Once cooled, you can store it in the refrigerator for up to 5 days. As a meal prep option, I like this filling best when served with rice in a fajita bowl instead of on a tortilla.

Freezing: You can freeze this rotisserie chicken fajita filling, but the onions and peppers may not have the same texture after thawing. Freeze in an airtight container or freezer bag for up to three months. Let it thaw in the refrigerator overnight and warm over the stove or in the microwave until warmed through.
