I rarely cook a meal for just myself. Either I cook for my housemates, or one of them cooks for me. It saves a lot of time, because cooking scales sublinearly. It's also cheaper and tastier (I put more effort in if I'm cooking for others).
She used to spend an hour a night making meals, now she gets the week done in a couple of hours (she is a stay-at-home mom and the only one capable of making a meal that's edible in my house).
