This tastes wicked on the BBQ:
Tandoori chicken -
Get some small skinned chicken breasts (on the bone) / thighs and make deep slashes in the flesh.
Either cheat & buy the sauce, or try:
couple of TBSP vinegar
same quantity lemon juice
4 TBSP vegetable oil
at least half a bulb of finely chopped garlic

6-9 TBSP hot curry powder
1/2 pint good quality natural yoghurt
red food dye
Mix it all up, adding sufficient food dye to give a deep red colour. The qualtities can be adjusted - go by the 'feel' of the marinade (some yoghurt is very thick & you may need to thin the marinade). You will need that large quantity of curry powder, as it is just a coating.
Place the chicken in the marinade, making sure the sauce gets right into the slashes. Marinade for 12 hours at least - the longer, the better. Marinade it in the fridge in an AIRTIGHT container - everything else in the fridge will taste of garlic otherwise... much as I love garlic, garlic milk is going a bit too far.
Chuck the chicken on the BBQ & cook through
It works better if the BBQ has a lid.
Do not worry about a little burning: proper tandoori chicken is cooked at very high temperatures in a clay oven (tandoor) and you are trying to emulate this.
If you cannot get small chicken breasts / thighs, then it may be wise to part-cook them in a microwave first, to avoid that 'burnt on the outside, raw on the inside'.
To serve -
Make a mint raita by mixing pre-made mint sauce with natural yoghurt to taste.
Serve with rice, raita, salad and praps a few coarsely-chopped fried onions.
