Heat the oven to 400F.
Prepare your baking sheet with a silicone mat or parchment paper, lay down sliced lemons.
Place salmon on top of the lemons. Add some salt, pepper and steak spice.
In a small bowl, mix oil, dijon, maple syrup, dill, garlic powder and mix until all blended together well. Then brush this marinade onto the salmon. Let marinade for as long as possible but can be cooked right away.
Cook for 12-18 minutes depending on the thickness of the salmon. Once salmon is pretty much done place the salmon on the top rack of your oven and broil for 2-3 minutes, until charred.
