L just solved a problem I seem to face after every family trip: the post-trip meal.
I hate coming home from a trip and having nothing in the fridge for dinner that night. The kids are cranky from traveling all day, we need to unpack, and often get ready for school/work the next day. And, I don't really want to stop at a local fast-food restaurant on the way home.
Since I often need to go to the supermarket before a long trip to get snacks, etc., I now pick up a bag of frozen ravioli, tomato sauce, frozen veggies and a loaf of italian bread. The bread goes in the freezer, with the veggies, and ravioli and it's an easy and quick meal for the evening when we arrive home.
Another good item to have in your pantry — a box of shelf-stable milk (or soy/rice milk) for cereal the next morning. OR…an unopened carton of ultra-pasteurized milk in the fridge. Ultra-pasteurization pushes "best used by" dates several weeks into the future.
What supplies do you keep on hand to make post-travel "reentry" easier for your family?
