Cut the chicken breasts into small, thin strips or bite-sized pieces for even cooking.
In a mixing bowl, combine the chicken with taco seasoning, lime juice, olive oil, salt, and pepper. Mix well to ensure the chicken is evenly coated.
Preheat your air fryer to 380°F (190°C).
Place the seasoned chicken in the air fryer basket in a single layer. Cook for about 8-10 minutes, or until the chicken is fully cooked and slightly crispy on the edges. Shake the basket or turn the chicken halfway through cooking.
Wrap corn tortillas in foil and place them in the air fryer for the last 2-3 minutes of cooking the chicken, or warm them on a skillet.
Place a few pieces of cooked chicken on each tortilla.
Top with diced onion, chopped cilantro, shredded cabbage or lettuce, and sliced avocado.
Sprinkle with crumbled cheese and add a dollop of salsa or a few drops of hot sauce to taste.
Serve your Chicken Street Tacos immediately while everything is still warm. Accompany with lime wedges and extra salsa or hot sauce on the side.
