> That's not true. The vast majority of convenient off-the-shelf meat substitutes use soy or seitan to replace meat protein.
Indeed. I've seen a trend in new products using other stuff though. It's getting easier. But lets not forgot you can just buy proper whole food instead like fruit, beans, grains, vegetables, legumes and so on.
> Staying vegan while giving up soy and gluten means committing to a massive amount of meal-prep, and vegan food is already more labour-intensive in meal prep than the corresponding omnivore meals.
I think it depends on what culture you are from. In Denmark, it's normal to prepare food yourself. Sure, some buy ready-made food in stores, but I've never grown up seeing my parents do it, and I rarely do it myself.
> It would mean basically giving up on all restaurant eating everywhere.
All vegan-friendly restaurants I've been at have also had non-gluten bread and dishes not containing soy at all.
> I'm not saying it can't be done, but you should not downplay that with "easily".
I think that's subjective. If you're used to buy food that's already made, well, then, it probably isn't. If you are used to cooking yourself then it is.
