Cold potato, thick mayo and gherkins, gurt lush!
Yes cheese sandwich is prob my go to. Nowdays mostly in my panini toaster.
I do love marmite & cottage cheese on toast - as my ultimate Umami breakfast or late snack
But will pass on a potato sandwich - although I love potatoes (except boiled)
I'm veggie and lactose intolerant so no chicken or cheese, I love cheese, but I really can't eat it anymore.
Gherkins aren't slimy, they're vinegary and crispy, some people even get the big sliced ones and deep fry them like crisps, I've not tried those yet.
