Season salmon with salt and a tablespoon of avocado oil. Bake in an oven preheated to 450ºF for 5 minutes per half inch of thickness, or until the fish flakes easily when pierced with a fork or knife.
While salmon cooks, prepare the dressing. Combine all ingredients except the olive oil and mix well. Then slowly stream oil in to form an emulsion.
Flake salmon and let it cool for a couple of minutes.
Toss the lettuce with the dressing and top with sliced eggs, onion, olives, capers, and salmon.
