How easy would this be?
Wouldn't it just be great if there was someone who could come to your house, do your weeks worth of cooking for the family, portion everything up, store it in the fridge / freezer then do the dishes and leave?!
All you need to do is have a kitchen with some basic cooking equipment such as chopping boards, mixing bowls, pots, pans, knives etc. Ash will leave the kitchen exactly as he found it with all utensils cleaned – the only difference is your fridge will be full when he leaves!
