That's interesting cuz that's just about exactly where I am now, too. I've been vegetarian in the past, though not vegan, and I like the idea of not being overly rigid (which means leaving a loophole for the occasional sushi indulgence)
My 12-year old went veggie eight months ago and I've been sort of passively following along, mostly cuz I don't want to cook two different meals every night.
Given environmental concerns, the politics of global food distribution, personal economics, and general health concerns, it really makes sense today.
