I think it's a brilliant idea, not only for time-strapped people, but a great way to show them that cooking from scratch really isn't hard. In an age when it's so easy to pick up a ready meal or a takeaway, so many people never really learn to cook properly simply because they don't have to. I think our generation were lucky in that respect because a) we more likely to have been taught proper cookery at school, b) we were brought up by mothers who home cooked everything so it was seen as the norm for us, and c) we didn't have the range of ready meals and takeaways when we started out on our own, so we had to cook.
I can remember when we moved into our first house, a few weeks after we married, and I was waiting on delivery of a cooker, so I borrowed a little table top mini oven with 2 electric rings. I cooked a full roast dinner on it - chicken, roast potatoes, 2 veg, and even made stewed apples and custard for pudding!
