Add water into a pot till just about covers potatoes, then bring to boil. If using fresh, place fish in a steaming tray on top of pot, cover and steam for about 10 minutes, until fish and potatoes are cooked. Alternatively, you can broil the salmon for about 15-20 minutes.
Remove steaming tray and drain potatoes. Flake the salmon with a fork and mash potatoes coarsely.
Add rest of ingredients, except lemon.
Mix well and form into patties.
Heat oil in a pan over low to medium heat.
Cook patties 2-3 minutes per side, depending on thickness.
Serve with lemon wedges and a green salad.
