Combine ingredients for Artichoke Salsa except lemon juice in a medium-sized bowl. Add preferred amount of lemon juice (I usually start with 1/2 a lemon then add more if I need to) then stir to combine and refrigerate while you cook the salmon. Lemon-Artichoke Salsa can be made a day ahead of time.
Heat oil in a large skillet over medium-high heat. Season salmon fillets generously with salt and pepper then place skin side down in the hot skillet. Cook for 2 minutes then flip and cook for 2-3 more minutes or until filets are cooked through. Peel off skin if desired then place fillets onto plates, top with Lemon-Artichoke Salsa, and serve.
