Meat haters pizza.... bahaha cant wait to try that.
Anyhoo there are stacks of vegetarian cook books at my house. Here are a few which I have found most reliable and useful (and delicious of course).
"Veg Out- 60 knockout recipes for the laid-back cook"
"The essential vegetarian cookbook"
"Great vegetarian food"
And theres also THE INTERNET! yay! Kasquillions of recipes from a quick google search. Its also great as you can narrow it down to what you want (such as searching "quick vegan polenta recipe" or something)
Also, look in the pantry and at the back labels of some ingrediants, also a great source for recipes.
