vampirequeen, it's impossible to answer, as it all depends on which type you are talking about. It does seem odd to me, going veggie, yet wanting 'pretend' meat. Producing any meat, though, involves vast amounts of land for grazing and/or cereal production.
My friend recommends 'Thisisnotbacon', Gro 'sausages' from the Co-op and mushroom 'steaks' from Iceland, for taste.
I've been veggie for most of my life, and although I liked the smell of bacon cooking, the thought of actually eating pig put me off.
For the past decade, I've been vegan. Consuming dairy (with it's 'allowable pus content') became just too difficult because of the cruelty involved.
These days, I get through a lot of tinned lentils, chickpeas and beans for 'heartiness' with meals - and protein and iron content. Saturated fats are scarce with a meat-free diet, so there are obvious health benefits.
It's much easier now, with ingredients available everywhere and tasty recipes online.
