Preheat your oven to 400°F (200°C).
Lay a sheet of aluminum foil on a flat surface.
Layer the foil pack by adding the asparagus on the bottom followed by the salmon. Add the corn and cherry tomato, followed by a squeeze of lemon and a sprinkle of dill (if using). Place a few lemon slices on top.
½ bunch asparagus, 1 fillet salmon, ¼ cup corn, ½ cup cherry tomatoes, ½ lemon, 1 pinch dill
Bring the long sides of the foil up to the centre and fold them over to create a seam. Then fold the shorter sides in, sealing the foil packs completely.
Place the foil packs on a baking sheet and bake in the preheated oven for 20-25 minutes, or until the salmon is cooked through and flakes easily with a fork.
Carefully open the foil packs (beware of the hot steam) and transfer the salmon and vegetables to plates.
Serve immediately and enjoy!
