I'm not a veggy myself, but I occasionally have guests who are, and for my own use I'm always willing to try alternatives - for example, I use soya for spaghetti bolognese since it seems to make very little difference to the taste, I use Quorn's fake bacon since it's pretty much the same in texture and taste in a sandwich, and less fattening,
Anyway, the salami cost 70p for a 50g bit so I thought I'd give it a chance.
And the verdict?
It's fracking horrible... just plain nasty and fairly unhealthy, 261 calories in 100g and 14% fats. It consists largely of egg and vegetable oils, proteins, and fats, the least convincing imitation food I've ever tried - the ingredients include wheat and egg so they've lost the vegan and gluten-free markets.
It's just possible that cooking will improve it, so I may try a few bits in an omelette or something, but I certainly won't buy it again.
later Ended up cooking spaghetti Bolognese and adding slices to the sauce, which improved the flavour of the pepperoni considerably, though only by making it taste more like the other ingredients. Definitely not recommended, the meal would have been just as good without it.
