I know what you mean about the cheese -- it is very hard to give up, and the fake cheeses are pretty lame, especially if you want them melted. Veggie slices aren't too bad, but they don't melt well. I'm finding eating vegan VERY enjoyable because I love to cook and I've been experimenting with all kinds of ethnic recipes. Americans eat tons of meat, but most of the rest of the world doesn't. Try Indian, Israeli, and Moroccan recipes, and learn to use spices and herbs.
There's a good vegan cheese company in NZ luckily for me, I use the stuff a fair bit and tastes pretty damn good.
Think it gets imported from the UK as it's about twice the price of normal cheese lol.
