I think mine is avacado, chickpea and sun-blush tomato on malted bread.

I presume it would not be the same for the prawns?

JewDaMacabee, I like the sound of that, except for the beef.

I am vegetarian, so the chances are slim to zero.

Branston pickle and cheese

agrees with holidaygrouch. I'd have to say that that's my fave.

I wish I could tell you but I haven't a clue (aside from the pickle part) I lived off it when I was growing up. Not so easy to get in the US

We can sell it to you...

luckily I have a mother who's great at finding English food no matter where we live. Couldn't live without Marmite either.
