Mix chicken, tandoori powder, chilli powder, cumin powder, olive oil, salt, garlic, coriander, Samyang sauce, and lime in a bowl, and allow chicken to marinade for at least 30 minutes in the fridge.
Preheat oven to 180°C and prepare chicken tikka by alternating the chicken with onions as well as green, red, and yellow bell peppers onto bamboo skewers.
Lightly oil the pan before placing skewers to avoid sticking.
Cook in preheated oven for 25 minutes, turning once in between. Serve hot.
