Foil packets are a convenient and mess-free way to cook salmon. Simply place the salmon fillets on a sheet of aluminum foil, along with some asparagus spears, and season with salt, pepper, and your choice of herbs. Fold the foil into a packet and bake in the oven until the salmon is cooked to perfection. This cooking method ensures that the salmon stays moist and flavorful, while the asparagus becomes tender and slightly charred.
