Where Does It Go?

For the month of June my husband is traveling for two weeks, we are on vacation for one weeks, leaving one week when the whole family is together and at home, where I need to plan meals. For the two weeks my husband is gone our dinner menu is simple: chicken nuggets, pirogis, pasta, and pancakes. During vacation we will be cooking our own meals, but with three other families sharing the same house the food responsibilities are spread out. So how, with such simple menus and a vacation in the near future, have I already spent two-thirds of our food budget the second day of the month.
