I notice a lot of threads about people not wanting to spend time cooking.

What percentage of time do you think paleolithic man spent on food per day? Perhaps 20-40% of waking hours spent hunting, gathering, preparing, eating?

Today almost everything is done for you, the food is all waiting just for you in the grocery store, and in many cases they will deliver those groceries to you. So if you spend 1-2hrs cooking that's only 6-12% of your day. It only takes one trip to the grocery per week, because we have an invention called the refrigerator, so add 1hr per week.

If you can't even do that maybe rearrange your priorities!
