Mix the tikka paste, yogurt, lemon juice and zest, salt and pepper in a bowl, then toss in the boneless skinless chicken thighs, pepper and onion pieces and leave in a fridge to marinate, ideally for 30 minutes. When ready to cook, thread the chicken, pepper and onion onto small skewers.
Select Air Fry at 355°F / 180°C for 10 minutes, turning the skewers when prompted.
Once cooked, assemble the wraps. Spread on some raita, add little gem lettuce and the chicken off the skewers, then top with fresh mango.
