For enhanced flavor, consider adding a splash of Worcestershire sauce or a drizzle of balsamic glaze before sealing the foil packet. Feel free to experiment with different types of mushrooms, such as shiitake or oyster mushrooms, to create a unique flavor profile. Ensure the foil packet is tightly sealed to prevent steam from escaping, which can result in drier vegetables. A double layer of foil may be beneficial. Monitor the grill temperature closely to prevent burning. If the vegetables are browning too quickly, reduce the heat slightly. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave before serving.
