Questions on going vegetarian

Today one of my badminton friends told me he wanted to be a vegetarian. I was curious whether he was serious about it, so I asked him why and he said he like animals. But his diet do not have much vegetables and he was thinking if he's able to get enough protein or be nutritionally adquate. I guess that's what many people are concern about when they are thinking of going vegetarian. Another thing he was asking if veg food it boring. If you are also asking questions like those my friend asked please check out the "Becoming vegan?" section on the side column of the main page, it contains some information a new veg*ns needs.
