Wanting to become a vegetarian..? Help?

[Naturul]

I've been wanting to be become a vegertarian but don't know how to start? I live in a house full of meat eaters, no one in my family is a vegetarian so it's a bit difficult since they only feed you meat and such plus I'm only 15. Nobody in my family eats very healthy and only eat very small snacks and junk food ( and yes I am guilty of that ) i need ideas of some vegetarian foods? thanks
