Bread and Onions in Old Books?

Question

A few of the old books that I've read have talked about eating "bread and onions". For instance, you go into the central market and that's what you come out with. It seems an odd combination. They are English books that I'm talking about. Can any English people chime in? I'm American so perhaps I'm a bit out of the loop, as it were.

How do you see these two things going together? Uncooked onions ... cut? bitten into like an apple?!!! shoved in the bread?

Thoughts?

Answer 1

It is probably where they baked onions and bread in milk.

Cheap and cheerful.
