Mix the chicken thighs with the olive oil, smoked paprika, cumin, coriander, chilli flakes and salt until evenly coated.
Air fry at 190°C for 12–15 minutes, or until cooked through and lightly golden. Leave to rest for 5 minutes before slicing.
While the chicken cooks, prepare the pico de gallo by mixing together the tomatoes, onion, jalapeño (if using), garlic, coriander and lime juice. Season with salt and pepper.
Heat the brown rice, black beans and sweetcorn until warmed through.
Divide the rice between two bowls. Top with the black beans, sweetcorn, sliced chicken, avocado and generous spoonfuls of pico de gallo.
Finish with a squeeze of fresh lime juice and serve immediately.
