Q: I've been vegan for about 4 years now, and I've been cooking all of my meals for 2 or 3. I've spent over $100 on a shelf full of vegan cookbooks. This one is the best I own. It's the only cookbook I have that has recipes that make food that's outright better than anything I ate before I went vegan! Ever since I started making my own vegan pizzas, I absolutely stopped missing the greasy things that I'd been getting delivered, and the pasta recipes here are the best I've ever had.The only problem with this book is that the recipes can take a while to prepare. If you're not a big fan of cooking, this probably isn't the book for you. But if you're glad to spend an hour in the kitchen making a meal and want to have some great vegan food, this book is a must!
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
