For an extra layer of flavor, consider marinating the pork tenderloin in the sauce mixture for at least 30 minutes before assembling the packets. Feel free to customize the vegetables to your liking. Snap peas, mushrooms, or baby corn would be excellent additions. Ensure the foil packets are tightly sealed to prevent steam from escaping, which is essential for even cooking and retaining moisture. To prevent sticking, lightly spray the foil with cooking spray before adding the ingredients. When grilling, be mindful of flare-ups and adjust the heat accordingly to prevent burning. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.
