Preheat oven to 400.
Line a cookie sheet with parchment paper and spray with avocado oil.
Place salmon pieces on cookie sheet. Spray them generously with avocado oil and season with sea salt and pepper (or lemon pepper seasoning).
Slice lemon into thin slices and add on top of the salmon. You will probably need 2 circular slices per piece of salmon. Add more seasoning on top of lemon if you desire.
Bake for 10 minutes and broil for an additional 2 -3 minutes.
