Something like: "I was an intermittent cook, because I need to sell, and manage my (small) business too.
In my case, cooking both soups and main courses, and some deserts occasionally was frustrating. Cooking times are always slightly different...
I increased my productivity and my fun tremendously when I switched to only eating polenta."
I hope this does not come off as offensive, which was not my intention, instead, I hope this serves as food(pun intended) for thought and reflection.
