There are plenty of websites! vegetariantimes.com vegweb.com vegkitchen.com There are a few! Get a cook book too! Cooking stuff isn't so hard. =P
Nah cookings really really easy. Start small...get a wok and chop up a load of veggies and fry them together with some soy sauce or whatever you fancy for 5 minutes Then work your way up until youre baking cookies and cakes and you wont be able to stop I started learning to cook when i was 12 and had it pretty much fully mastered by 13. And that was on my mothers really old, half-broken cooker! Good luck
http://www.theveggietable.com/ is a pretty good site as well. But really if you just do a search for vegetarian recipes you will get more than you could possibly make. Just search around for things that sound good to you and start cooking. It is not that hard at all. You just have to start.
Cooking takes practice! You can't just wake up one day and be an amazing chef. I would say to get a basic cookbook, even one with meat, to get basic knowledge of foods, how to prep them, etc. I just learned by watching my mom and being the only one in the house that could cook at all when I moved out. Vegetarianism will be much more rewarding for you if you become self-sufficient and learn how to cook. Maybe try baking, too! It's fun!
