Good points. I'd only suggest living with co-founders if you know them well enough and can jive on a regular schedule. I mean, if you get sick of your co-founder, maybe he/she wasn't a match in the first place?

As for the time preparing the meal (from researching recipes to cleaning up), I'd say it can take less than 1.5 hrs per day total. Imagine buying in bulk, cooking a large, delicious stew that can last a couple days (just warm up the meals in a microwave), and voila. Time and money saved.
