Drain the salmon well and remove any pieces of cartilage. Tip the salmon into the stand mixer bowl and mix with the breadcrumbs, lemon zest, pimentón and egg into a firm paste.
Shape 4 burgers. Cover them and place in the refrigerator for at least 30 minutes to firm up.
Meanwhile make the tuna wasabi mayonnaise. Add all the ingredients into a blender or food processor and puree into a smooth sauce.
Bake the salmon burgers at medium heat for 4-5 minutes on each side until golden brown. Serve on brioche buns with lettuce, red onion and some tuna wasabi mayonnaise.
