Dry roast the minced cauliflower in a big frying pan or a wok until it begins to colour and smell nice. Pop it in a big bowl.
Add the shallots, chiles, and coriander and mix it all up.
In a little jar combine the lime juice, fish sauce, sugar,pepper, and rice powder. Shake it well,and pour it over the cauliflower.
Toss it well to coat everything.
Serve it in a big bowl with a plate of lettuce leaves. Use the lettuce leaves to hold a spoonful or two of the laab to carry it to your mouth.
