cheese and onion spread with either cucumber or tomato slices.
closely followed by coronation chicken and lettuce
mum used to make her own bread by hand every sunday (because the oven was on to do the roast) and for sunday tea we had bread still warm from the oven. She would slice it and butter it (with real butter) and we'd have a do it yourself kit. we would choose from jams, cheese, bovril, tomatoes, lemon curd etc etc and make our own at the table as we ate. cheese and onion spread was always my favourite on warm bread.
it used to give us indigestion because it was so fresh, but i have never had anything so nice to put sandwich fillings in.
