For me personally, I watched a video about a year ago and haven't put any sort of meat in my mouth since (not even fish). I eat a lot of nuts, beans, tofu, soy products, fruits and veggies. I feel great, the healthiest I have ever felt in my entire life!! I love it. I have now slowly started to remove other animal products from my life, no eggs, cheese, any dairy really. Occasionally I put cream in my coffee, I am trying to stop that as well. I don't know if you facebook but there is a great group on there called "Vegetarian" it is a non-profit organization, lots of good articles, recipes for both vegetarians and vegans. Good luck!!
It's really tough making a complete diet overhaul in one big step. If I may suggest something, turn to vegetarianism in baby steps. Perhaps start by removing all red meats from your diet, and look for ways to supplement the protein you'll be missing out on (try beans, cheeses, eggs, etc.). After you have that under control, remove poultry, etc. It's a lot easier to stick to it when you've had a chance to train yourself into it as opposed to shutting yourself off from all the things you're familiar with.
I think falafel and tofu are great substitutes for meat. You can fry falafel and replace hamburger patties with it. Most sandwich take-away places have falafel burger/wrap options now a days too which is great. You can still eat most meals, just without meat. Pasta is great on it's own or with a sauce, noodles or rice with a side of assorted veges :) Sushi places now have vegeterian sushi with things like potato, or cream cheese and pineapple in the sushi (soooo yummm).
I'm a vegetarian too and when I first started being one, I found lots of things to eat without meat
Try Quorn or other meat substitutes. If you still eat fish then you can still have that, lots of pasta products, potatoes, eggs, soups - loads! Beign veggie isn't always about eating salads xD Check out some vegerarian recipes online or in a specialised veggie cookbook :)
a vegetarian is someone who doesnt eat any meat (this includes chicken and fish which obviously comes from an animal that needed to die so you can eat it) a vegetarian does eat animal by-products (like cheese and milk) only vegnas choose not to eat animal meat or by-products. if you cant get the nesecary nutrients from your diet consider suppliments
