I get that Paul.
Actually it's not steak and kidney it's amazon pie, snake & pygmy.
If you fancy trying a chip butty heres the recipe, it's a bit complicated but just do your best:
Butter two slices of bread.
Put a handful of french fries on the one slice.
Add a dollop of brown sauce (HP or A1).
Cover with top slice.
There you go, chip butty( you would probably call it a french fry sandwich). I told you it was complicated
