About 50% of my meals cooked at home are vegetarian (not vegan, though I have had some very good vegan recipes), while the other 50% are fish with vegetables. I love meat and all, but I don't particularly miss it for dinners, if I want some I'll just grab it at lunch.
if it's vegan food, I much prefer straight vegetables instead of veganized meat substitute (universally awful). The Candle Cafe Cookbook is pretty good, and I always like the Moosewood books (also not "true" vegan). As mentioned, Plenty is also excellent.
