We actually cook slightly more on the road than at home (we have an apartment with full kitchen on the road). She usually gets the menu together and I do the cooking. Unfortunately, neither of us likes to clean up.

When we get home on Fridays, we are usually too tired to cook or even shop for groceries, so we tend to get takeout or go out someplace, then stretch the leftovers until we leave again Sunday afternoon. I hate to do a lot of cooking and then leave something in the fridge to go bad if I don't have time Sunday to consume or store it properly.
