What you have described sound like what we call prawn crackers. I've never seen them in an uncooked state but I imagine they start out as discs, but they don't end up the shape of whole kiwi fruit, so maybe there is something different. To look at they are like extra thick, puffy, light versions of potato crisps (what you call potato chips) and they snap cleanly but are rather oily. I am red-green colour blind, but my impression is that they probably have a very pale pink tinge which makes them look off-white to me. I guess the colour comes from the prawns. No one ever orders them but the Chinese take-away place always gives them to you anyway!

Potato chips to us are what you call French fries, though traditionally ours are of bigger cross section (about a quarter inch square) than the McDonald's variety. The thin French fries are worse for you as they have a greater surface area per kilo, therefore taking up more oil. But they cook quicker.

Gotta go. Have a good weekend.
