I was walking out of the auto parts store once and some guy asked me if I wanted some zucchini so I said sure. He handed me this 6-8 inch diameter by nearly 2 foot long monster. Didn’t have a clue what to do with it so I did a web search and came up with zucchini pickles. None of us really like them so I still have several canning jars full.

That is a stuffer.
You slice in half longitudinally, scrape out the seeds, then fill it with your favorite meatloaf or sausage type stuffing, and bake, with a little water in the pan, until done. In the last part of baking, top with tomato sauce or pasta sauce, and cheese.
It’s usually best to par-cook the stuffing, so it fully cooks before the zucchini shell is overdone.
Don’t ask for time/temp: it’s a seat of the pants thing, though a 350 oven is a good starting point.
