Take a hot oven, a length of foil, and a few select ingredients and what do you get? Divine dinners that require little prep work and no pots or pans to clean. Tightly wrapping foods in individual foil packets allows them to steam-cook to perfection while the flavors harmonize. Packets can be cooked in an oven or on a grill on medium-high. Either way, the cooking time is the same for each recipe. And since each packet acts as both main and side dish, all you need are some steamed greens, grains, or a big tossed salad to complete the meal.
