I spend around $30 a week. I've gotten better about being realistic about how much food I'm actually going to eat so I don't have to throw a lot away. That number might go up to $40 if I'm having friends over for dinner, which I do about once a month. I don't drink and I make most of my food from scratch, which helps me keep my spending in check.
My credit card is down to just under $400, which was my goal for the month. Woohoo!
Here in Austin, you can find amazing breakfast tacos for $1.25, but you need at least two (or three or four...) to eat at a time.
