This site www.middagsfrid.se offers something more. They charge 725 kr (795 kr 1/1 2008) per week for a grocery bag filled with what you need for a weeks worth of dinners for four people, including detailed recipes. They aim to plan the menu so that you won't spend more than 30 minutes cooking, apart from any time in the oven (when you don't have to actively do any cooking).
We have a 4000 kr/month food budget at the moment (not just used for food though), buying bags from Middagsfrid is less than that. And we'd have our menus planned out. And we'd be eating healthy and ecological meals.
