What is pooh as in Fijian food?

It seems you might be thinking of a Fijian dish called "palusami". It's a popular traditional dish made with taro leaves cooked in coconut milk and often includes other ingredients like onions, garlic, and sometimes meat or fish.

"Pooh" doesn't seem to be a common term in Fijian cuisine. If you have any other clues about the dish, such as its ingredients or how it is prepared, I might be able to help you further.
