This seems like something that won't ever work because there's like 10 decisions that the computer has to make that it can't possibly know unless it's either a mind reader or has a crazy level of surveillance on your life. How does it know what's in your fridge or pantry and the quantities of each item? How does it know how many people you're cooking for? What if your kids or spouse aren't going to be home a given night -- do they all have their own calendars that are impeccably maintained and synced to yours? What's your budget and do you really trust it spending your money? What if there are several options for each ingredient, how does it know your preference? Perhaps you prefer to buy certain ingredients at Costco and were planning on making a trip tomorrow, how does it know not to order stuff you buy from Costco in your grocery order?

Even if it could figure everything out, is this a problem that people actually have? I'm not even being facetious, but you're describing someone who cares enough to spend time cooking and clearly has a preference on what they want to make, but doesn't care enough to actually select the specific dishes.
