I can help you with a few, Rustpot

Chickpeas are also called Garbanzo beans (and I know fitday has those)
Swede is a rutabaga
gooseberries are just gooseberries as far as fitday is concerned ..? (I found them there.. type in "goose" and its halfway down the page)
Mange tout (lol "eat all") are snow peas over here.

P.S. thanks for the inadvertent chuckle - your subject line brings to mind a skit I saw with Christopher Walken "you say tomato and I say tomato" (tomato pronounced the same way both times)
