This recipe uses what I had hand in the fridge or freezer. I assume you will have some of the items at the ready. I’d be shocked if you have all of them. That’s not the point. This isn’t a follow-along recipe.  It’s a reach-in-and-grab demonstration. Dinner shouldn’t be prescriptive.  Improvise. Let your imagination fly and see what meal emerges from the oven once heat and time have worked their magic.
