anyone who eats oysters in not vegan or vegetarian, IMO, I say this as a former lacto ovo vegetarian, who got so fed up of Asian restaurants listing fish based meals as vegetarian. It confuses the issue.
If your Hubby wants to eat meat, good for him. It is , after all a vacation. BTW, falafels spike me. (even without the pita) Nothing wrong with a bit of sauce now & then,.
