Very interesting. I look forward to reading a summary of your month of eating in, but one thing to be careful of is that because you won't have any staples/basics, you should be planning/ready to spend more than you hope your 'average' costs will be. For instance, olive oil, salt, pepper, other seasonings to taste, can all add up fairly quickly but you'll only need to purchase them every few months, if that. Especially if you find some good bulk food stores, you could stock up on non-perishables for a couple of months: while it looks bad on a one-month budget, it'll look good on a three month view.
