I´ve been a vegetarian for more than 3 years, and I learned one thing well:to make things easier on yourself
you´ve gotta start cooking so you don´t fall into the pizza-pasta-bread-potato trap. Maybe a little course for starters, but I really gets you going and lets you see all the choices besides the boring salads.
So when you solve your meals at home by cooking a little bit, you save those more popular dishes for dining out.
I don´t diet at all, I eat eggs and dairy, and sometimes people look at me as if I was "cheating" because I´m eating pizza or frenchfries. Vegetarianism is not about dieting but about not eating dead animal´s flesh, for many reasons (to each its own). People can look at you or even make comments, but nobody is gonna put a gun to your head to force to eat what you don´t want.
I don´t declare myself a "vegetarian" in public, and I only say that I don´t eat meat when somebody asks me a straight question. Oherwise I don´t mention the issue. When I´m dining at somebody´s who doesn´t know that I don´t eat meat, I stick to the salad or some side stuff like potatoes, etc, and I simply don´t mention my diet at all. You´ll be surprised to see how many times people just don´t notice you haven´t touched the meat.
Anyways, the best thing is when you arrive to that point when you consider "your" food so much better than anybody´s else, and you dont yearn for meat, at all.
So my advice for begginers is: If you still feel the craving, go ahead and eat meat. But if you give it a try for more than 3 or 4 months..... you´ll never go back.
