Aside from vegan (personally think there crazy, especially raw vegan)
That is my main reason for not taking it serious when i vegetarian confronts me. (they do) sorry dont take offense. It seems like alot of people that go vegetarian like to make it well known how much better it is then people who choose to follow instinct.
I see raw vegan (living foods) as the most instinctual way of eating possible! I still like pizza though.
Not to nitpick, just inform, but Parmigiano Reggiano isn't vegetarian as it's made with cow rennet.
You can make a chia (or ground flax) egg for baking; 1 tbsp chia seed to 3 tbsp water, let sit for 10-15 minutes until the mucilage becomes "eggy"
