My fiancee and I are in a similar situation. We've taken a less radical approach, we simply cook twice a week and make enough to cover the rest of the week with some to spare, which we freeze. It doesn't usually take much extra time to double or triple one recipe at a time. Then, when a week is too busy to get in 2 cooking nights, we just start pulling from the freezer. Meals that work especially well with this approach are soups, chilis, and fish dishes. Frozen salmon + herbs and lemon sauce, wrapped in parchment and frozen by the dozen, is our fast food. Just throw it in the oven for a few minutes and you've got a healthy, decent meal with no cleanup.
