Left home, campus food was ok, but I found it was cheaper to make my own food. The dorms did not allow open heating elements, but we snuck in a rice cooker and made a variety of foods out of it, including rice, scrambled eggs, and simmer-soups. They also had a kitchen, but only one to share between hundreds of students. I would use the kitchen to make more complicated foods when I could, in big batches so they'd feed me all week.

I went vegetarian because meat's expensive (and for environmental and health benefits), and learned how to cook veggie burgers, vegan ice cream, and a bunch of other things...

And then I no longer lived at the dorms, and started cooking my own food indefinitely. I have more money now, too. : D
