It's hard.
Previously I was vegan, but I'm not any more, just vegetarian (long story & I do feel better when vegan, but can't 'get there' again right now).
I did well on BIWI's (low carb) boot camp, she's a STAR 🌸, I had a medical dx and I don't know how I'd have got through it without her, I honestly don't.
Unfortunately, for a vegetarian who doesn't eat eggs & hates cooking too, it's really, really hard. I've been off the wagon for a couple of years now and I've only just been able to face Greek yogurt again recently and I still can't face almonds.
Waitrose stock Taifun's basil infused tofu (in the fridge section, near the dips, olives, quorn 'ham' etc) which I really like. It's very firm and you use it as it is, cold, much as you'd use ham for example.
But getting enough protein & fat is difficult (butter, butter, more butter) and much more difficult for a vegan.
I lost 3 stone. Sadly it's all found its way home again.
Nothing else works for me though.
