Leek (and in this case turkey)

Leeks are green and white and long,
Is there anything they've done that's wrong?
Have they started wars or slaughtered whales?
(They've some mild association with Wales,)
They can turn their talents to soup or stew,
They're versatile and under used,
They fit the bill and feed the weak,
So let's give some recognition to the humble leek.
