You can make dinner or even just order from your favorite Chinese place and dish it out onto plates. The point is to eliminate the need for her to think about it, or to even lift a finger. If she goes out sometime in the afternoon, by the time she returns you should have dinner well under way, the table should be set, a glass of wine should be poured and ready for her, and perhaps draw a warm bath. Again, don't leave a mess in the kitchen.
