<prompt> Human: I want to try and cook at home more, but I always find that I buy too much food like veggies and fruits. Is it beneficial to just buy the stuff I need to make tomorrows lunch, and then spend maybe 10 mins everyday doing that? Im trying to plan out my meals, but I dont want to end up throwing out a bunch of rotting food.  <response>: If you plan your meals a week at a time, you can shop for them all at once and save time. And you can save money, too.
