In a large skillet, heat 1/2 T olive oil. Using your hands, scoop even amounts of salmon mixture and roll into balls, patting into cakes. Place in the pan and cook 3-4 minutes on one side. Drizzle pan with remaining olive oil and flip cakes, cooking for an additional 2-3 minutes.
Remove cakes from pan, top with Remoulade Sauce and serve immediately.
