I am so excited to see your post!
I've been a vegetarian for over five years, and I've never looked back. I think it is a great choice, not only because eating meat-free dishes can be very frugal, but because meat-free choices are better for your body. If you're worried about not getting enough protein, concentrate on incorporating beans and tofu (and dairy products, if you want) into your diet, and you'll be just fine.
I have tons of great books at home - I'll take a peek at what I've got and let you know. Check out the cookbook section at your local library; they might have something to get you started. There are zillions of vegetarian and vegan cookbooks on the market.
I have been considering the switch to becoming vegan for some time now. I think it would make me a much healthier eater - I just have to take the plunge.
I'm so glad your husband is supportive! When I met my SO, he wasn't vegetarian, but he listened to what I had to say on the topic and decided to quit eating meat. He still eats fish occasionally, but that's it. My mother is a vegetarian, and my father a meat-eater, so it can be done either way.
Here's a
