I'm going to say:

1. Mango
2. Yoghurt
3. Coconut
4. Lime
5. Onion

But the real question is this: Has anyone EVER been given less than far too much of these? Even if there are 20 of you, you get so many you'd be hard pressed to make a significant dent in them.

How much do they expect you to eat before the meal even begins?

Do you think they 'recycle' them? Clearly it would be massively against health and safety but I don't really trust restaurants to stick to those sorts of guidelines for some reason.
