Read that you are a busy student, if you have a Trader Joe's look for both the Fresh and Frozen Riced Cauliflower. Someone on a FB page said that Walmart's now carries it too.
In the winter when fresh caulifower is expensive and looking sad, I buy the bags of frozen at Walmart's to make the mashed recipes (add garlic), also the bags of frozen cauliflower and Broccoli... that makes a pretty pale green base for any recipe.
