Your guess would be as good as mine as to why I made ratatouille just now at 1 AM.
I generally tend to view anything that doesn't involve meat as fairly easy when it comes to the labor, even if it isn't.
I've had some eggplants sitting around and I've been meaning to do something with them. They gave me the inspiration to make ratatouille, but they're still sitting on my counter because I bought another eggplant for my ratatouille purposes when I was at the store earlier. I did not have my phone on me, so I could not look up a recipe for ratatouille to make sure I had all the ingredients. I decided I was gonna wing it (improvise).
