Ingredients
  

  • 1.25–1.5 pounds boneless, skinless chicken breasts (or thighs), sliced into thin strips
  • 1 large red bell pepper, thinly sliced
  • 1 large yellow or orange bell pepper, thinly sliced
  • 1 small red onion, thinly sliced
  • 2 tablespoons avocado oil (or olive oil)
  • 1 teaspoon fine sea salt
  • 1/2 teaspoon black pepper
  • 2 teaspoons chili powder
  • 1 teaspoon smoked paprika
  • 1 teaspoon ground cumin
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon dried oregano
  • Pinch of cayenne pepper (optional, to taste)
  • Juice of 1 lime, plus extra wedges for serving
  • Fresh cilantro, chopped (for garnish)
  • Low-carb tortillas or large romaine/butter lettuce leaves, for serving
  • Optional toppings: sliced avocado, sour cream, shredded cheese, sugar-free salsa

Instructions
 

  • Preheat the air fryer: Set to 390°F (200°C) for 3–5 minutes while you prep the ingredients.
  • Slice everything evenly: Cut chicken and vegetables into similar thin strips. Even sizes help everything cook at the same rate.
  • Make the spice blend: In a small bowl, mix salt, pepper, chili powder, smoked paprika, cumin, garlic powder, onion powder, oregano, and cayenne if using.
  • Season the chicken: In a large bowl, toss chicken with 1 tablespoon oil and about two-thirds of the spice blend until well coated.
  • Season the veggies: In a separate bowl, toss peppers and onions with the remaining 1 tablespoon oil and the rest of the spice blend.
  • Arrange in the air fryer: Spread the chicken and veggies in a single layer in the basket. Avoid overcrowding. Cook in batches if needed.
  • Air fry: Cook for 8–10 minutes, shaking the basket halfway. Chicken should reach an internal temperature of 165°F (74°C) and veggies should be tender with some char.
  • Finish with lime: Transfer to a bowl and toss with fresh lime juice. Taste and adjust salt if needed.
  • Serve: Pile into lettuce wraps or low-carb tortillas. Add avocado, sour cream, cheese, cilantro, and extra lime as desired.
