"Inventing meals" is my wife's specialty. Tho she calls it by the most colorful name of "Sh17 in a pot"... Predictably we don't have written down recipes for that sort of stuff, but it's surprisingly good eats.

I wing my cooking, but with a goal in mind, so it's not like I invent something. More like my interpretation of a dish. More often than not it turns out edible, much to the wife's relief.
