Usually meat flavoured crisps are veggy-friendly but in this case it's an unmistakable flavour - you wouldn't get such a pin-pointed steak flavour without there being beef in it.
The Smoky aroma seeps through the crisp making for a smooth finish.
Chimichurri is an Argentinian recipe for steak - usually containing a mixture of Parsley & Oregano - and it's a flavour that goes down really well. What a treat!
Another bullseye from Walkers sensations.
