My wife is vegetarian, so more often than not, I'm eating that way. Boca and Morningstar taste awesome, but my problem is that I truly continue to feel quite hungry by foregoing meat in the meal. So even if these veggie options "behave" as they should, I think the bigger problem is that, for people like me, the lack of animal protein propagates as hunger, and I never feel fulfilled, and consequently am irritable.
