To meal prep cook the chicken and peppers in the air fryer as the recipe instructs. Skip adding the mix to tortillas and crisping them. They won't hold up. Instead, pack the fajita mixture into meal prep containers and add tortilla/s to a zip top bag. Reheating will depend on what you have available. If you DO have an air fryer available continue with the steps in the directions. If you take these to work and don't, heat in microwave for 20 seconds.
