I haven't quite figured out our food budget. Actually, I have figured out our food budget, but I haven't really implemented my knowledge and made the right decisions. As a result, we tend to eat steak and asparagus at the beginning of the month, and bagels with peanut butter at the end of the month. My body seems to be adjusting to this cycle.
It's not that there isn't money in the spending account, in the gas account, the savings account, one of the other 11 "accounts" we have arranged on a spreadsheet. It's a matter of discipline, of principle. With the right amount of planning, I can make substantial meals for one month on the budget we determined.
In my world, "giving up" looks like an extra bottle of peanut butter in my shopping cart. I currently have two in the pantry.
