Season salmon steak on both sides with lemon pepper seasoning (1/2 tsp on each). I like to cut small slits in the salmon and push more seasoning into it. Then, on medium high heat skillet.. melt 1/2 tbsp of butter around skillet and place salmon steak on top. Cut lemon in quarters and squeeze one quarter on top of salmon. Flip after about 3 minutes. Squeeze another quarter of lemon over salmon. Let cook for 3 more minutes, or until you're comfortable with how done it is. I like mine a little rare inside. If you're not sure just cut it a little bit and take a look at the inside. Then plate and serve extra lemon slices for more juice!
