Place red pepper, red onion, chorizo and tomatoes in the basket of the air fryer and toss with tongs to mix. 10 minutes at 200°C.
When the time is over, take the drawer out and add the chicken. Toss with the tongs to mix. 3 more minutes at 200°C. Toss again and serve.
Serve on its own or sprinkled with cheese. Sour cream goes great with it too, as does chopped fresh parsley or coriander
