PREPARATION:
Preheat Oven to 425˚F. Line rimmed baking sheet with parchment or silicone liner. Place salmon in the center, skin-side-down, drizzle with olive oil and season with garlic salt and black pepper. Bake uncovered for 10-15 min (depending on thickness), or just until cooked through. Remove from oven, cover with foil and rest 10 min. Flake salmon with 2 forks discarding skin and any bones then set aside and cool to room temp.
Heat a medium skillet over medium heat with 1 Tbsp olive oil and 1 Tbsp butter. Add diced onion and bell pepper and saute until golden and softened (7-9 minutes) then remove from heat.
In a large mixing bowl, combined flaked salmon, sautéed pepper and onion, 1 cup bread crumbs, 2 beaten eggs, 3 Tbsp mayonnaise, 1 tsp Worcestershire sauce, 1 tsp garlic salt, 1/4 tsp black pepper and 1/4 cup chopped parsley. Stir to combine. Form into patties (about a heaping Tablespoonful each) and mold with your hands into 2″ wide by 1/3 to 1/2″ thick patties.**
In a clean non-stick pan, heat 1 Tbsp oil and 1 Tbsp butter until hot then add salmon patties in a single layer. Saute 3 to 4 min per side or until golden brown and cooked through. If salmon patties brown too fast, reduce heat. Remove finished patties to a paper-towel lined plate and repeat with remaining oil, butter and salmon cakes.
