I wasn't aware that mixing flaxseed with water could substitute for an egg. Live and learn, I guess.
Do vegans eat anything with yeast, since technically, yeast is living? That could really complicate matters if you're making angel biscuits, which are yeast risen. I suppose you'd have to ask someone who is vegan.
I can see going at least part time vegetarian, but vegan is just too much of a commitment for me. I can't imagine giving up all animal protein. I know they say they don't miss it, but I think I would after a while.
