To make a healthy meal using aluminum foil, consider 'foil packet cooking'. Choose lean protein like chicken or fish, and pair it with a variety of colorful vegetables such as bell peppers, zucchini, and cherry tomatoes. Season with herbs, garlic, and a drizzle of olive oil. Fold the foil to create a sealed packet and bake in the oven at 400掳F (200掳C) for about 20-25 minutes or until the protein is cooked through and the vegetables are tender. This method retains nutrients and flavors while minimizing added fats.
