Taro is more filling than potatoes, as a vegetarian it is a very satisfying meal roasted with oil.
Quite a few people used to grow the Colocasi or Cypriot Taro around here, small offset tuber type, but haven't seen it for years in this grape and citrus area.
Old people have passed.
Also we have quite a few Pacific Islanders here now, so big tubers are available in shops.
When I was in Cairns, used to buy the PNG types from ladies at the market, Purple leaved black Taro's were nice to eat.
Also there are specific leaf types, with more edible leaves.
