Preheat the oven to 180°C

Grab a sheet of tinfoil and fold the sides up to create a box and lid large enough to fit the salmon in with some extra space on the sides

Slice the lemon and place flat in the tinfoil box (enough slices for the salmon to lay on)

Optional: spread some pesto over the salmon fillet

Place the salmon fillet on top of the lemon (with or without the skin on)

Optional: add some veggies in along the sides of the salmon

Drizzle oil and soy sauce over everything

Roll the tinfoil up so it becomes a sealed parcel, and chuck in the oven for 30 minutes

Remove after 30 minutes, open up and move all the food to the plate. You can drizzle the remaining sauces over the food
