If you don't have an 8- or 9-inch cast iron skillet, use a 1 1/2-quart casserole dish. Use the Dutch oven to cook the onion and garlic mixture in step 2; remove and set aside. Cook chard mixture as in step 3. Add onion mixture to turkey mixture. Transfer to the casserole dish. Continue with step 4, layering the phyllo over the mixture in the casserole dish.
