I have a binder that I keep to hold household information. I find it a little easier to find paperwork when it's not strewn about the house randomly (although my husband seems to enjoy the latter system). One subdivision of the binder is dedicated to food: the weekly dinner plan, grocery list, and recipes go in this section. I make up a weekly dinner plan on Monday, put the necessary ingredients on the grocery list, then go to the store. This plan makes a chaotic life seem a little less turbulent.
An additional tip: belonging to a warehouse club store may not seem feasible for two people (isn't that a place that sells 40 gallon jugs of sourdough pretzels?), but it is actually worth it for a lot of things, not the least of which is their meat section. Don't judge- Costco meats are good! I buy a package of individually wrapped boneless, skinless chicken breasts and a bunch of boneless pork chops, which I separate and wrap in saran before putting in the freezer. The only thing I have to remember is to take the meat out in the morning (which is a surprisingly troublesome task for me). Buying meat at the butcher every day is expensive and time consuming (it cuts into my E! News time) and it's not as good from the grocery store (sorry , Stop and Shop).
