Clean and cut the chicken into four pieces (two leg part + two breast part). For the marinade mix together garlic paste, salt, red chilli flakes, red chilli powder, chilli sauce, tomato ketchup, soy sauce and barbecue sauce. Marinate the chicken pieces in this mixture for an hour.
Place a thick barbecue iron griddle on live charcoals and smear it with three tablespoons oil. When the griddle is hot enough place the marinated chicken on it and baste with the remaining marination.
Cook till done (fifteen to twenty minutes) and golden brown in colour, basting with oil from time to time. When one side is cooked turn over and cook the other side similarly.
(You can also skewer the pieces and grill, basting with butter from time to time, till golden brown). Serve hot with onion rings, capsicum and carrot slices.
