It would be cool if there was a website where you could enter in your preferred macros for a meal and pick a fast food restaurant and it would use their nutrition info and a search algorithm to give you a list of your best options for that meal to get close. Maybe something like that already exists, but when I'm lacking time to cook, it would be awesome if I could just stroll into any fast food joint and know what to order to at least hit a good macro balance. Sure it wouldn't be very healthy since fast food has almost no micronutrients, but when traveling and such, it beats missing your macros too!
