Preheat your griddle to medium heat.
Season your salmon on all sides with a light layer of seasoning.
Cut the lemon in half, reserve one half, and slice the other half into ⅛” thick slices.
Add the oil to your griddle, then place the lemon half and slices on to char.
Place your salmon, skin side up, on the griddle.
After one minute, remove the half lemon from the griddle and flip the slices to get charred on the opposite side.
After your salmon has cooked for 5 minutes, gently flip it over with a spatula so that the skin side is facing down.
Squeeze the juice from the charred half lemon over the top of your salmon filets, then place the charred lemon slices on top of each filet.
Let the salmon cook for 7-10 more minutes or until they reach an internal temperature of 145°F.
Remove from the griddle and serve immediately.
