Pizza
As a college student, you probably donate a large portion of your money to the local pizza chain, especially since it’s an easy vegetarian option when you don’t feel like cooking. Making your own pizza allows you to be a bit more creative and is way cheaper. This is a perfect version in my book, because you don’t have to wait for the crust to rise. Try some soy pepperoni and see if your nonveggie friends notice the difference, or just stick to vegetables.
