Photos by Mitch Mandel  Here’s how to put them together:Heat oven to 425°F. Trim ends off 2 or 3 small zucchini and cut lengthwise into quarters. Put on a nonstick baking sheet, drizzle with olive oil, and season with salt and freshly ground black pepper. Roast 5 minutes. Meanwhile, wrap 1 slice prosciutto around each of 4 halibut or cod fillets (4 to 5 ounces each). Remove pan from oven, flip zucchini and push to one side, and put fish on pan. Roast until fish is just opaque and zucchini are tender, about 8 minutes. Top each fillet with a little pesto. Serves 4.
