Set oven to 400F/204C.
Lightly season halibut with sea salt & pepper.
In a bowl mix together the ingredients for the crust.
Lightly spray the top of the halibut with oil, then add tablespoons of the crust on top. Gently press it down into the flesh. Add the filets to one end of a baking tray. On the other end, add the asparagus spears. Lightly spray with oil then add sea salat & pepper.
Bake in the oven for 15 minutes, or until the fish is cooked through and the crust is golden brown.
Enjoy with fresh lemon and flake salt if needed!
