I have an air fryer that I can roast my veggies. I do a mixture of whatever I have on hand. Either spray them with cooking spray or drizzle with some olive oil and then roast them. God it's good. I'll have to remember your method. Minus the cheese.
My Italian step mother used to do it similar to you. In leftover spaghetti sauce (homemade Italian style). The zucchini would stay tender crisp.
