You'll feel better and it's likely to take you less time than ordering and waiting for something to show up. If you're just doing pick up, it will save you 2/3 of the money you're working doubles to make and then lighting on fire to eat fast "food".

If you've got a rice cooker and a toaster oven I've got a couple of recipes less than 10 mins of actual work. I understand not wanting to work too hard at it too though.
