Salmon and asparagus foil packets are a convenient and delicious way to cook salmon. Start by seasoning the salmon fillets with salt, pepper, and your favorite herbs or spices. Place the seasoned salmon on a sheet of aluminum foil and top it with fresh asparagus spears. Drizzle the salmon and asparagus with olive oil and lemon juice, then fold the foil to create a sealed packet. Bake the foil packets in the oven until the salmon is cooked through and the asparagus is tender. The foil packets help to lock in the flavors and juices, resulting in moist and flavorful salmon. Serve the salmon and asparagus foil packets with a side of rice or quinoa for a complete meal.
