I love crisps. They're actually my favourite food. It's so hard to choose just one.
I'd go with Walkers salt and vinegar if I could only have 1.
I prefer cheese and onion.and prawn cocktail but feel salt and vinegar might have more longevity.
I also love Seabrook prawn cocktail. And walkers roast chicken.
And waitrose essential mixed flavour 6 pack.
And all wotsits and skips!
