Combine the soy sauce, the ginger, garlic, juice of 1/2 lemon and zest of a lemon in a bowl. Brush the salmon fillets with the marinade and let sit for at least 10mins.
Place your salmon over the kale, add your chillis over everything along with the rest of your marinade.
Place a second sheet of parchment paper directly over the ingredients. Align it with the bottom sheet, then fold and crimp the edges of both sheets together all the way around to create a tight seal. Press firmly as you fold to ensure the packet is completely closed, this traps the steam inside while cooking.
Add your tray in the oven an cook for 20 minutes.
Plate the kale first, creating a warm bed.Lay the salmon on top. Finish with a squeeze of lemon juice and a generous drizzle of olive oil.Optional: add a spoonful of yogurt on the side for creaminess.
