Preheat the oven to 400 F
Line a baking sheet with aluminum foil and spray oil. Place red peppers, onion, along with garlic wrapped in foil to avoid charring and then transfer the baking sheet into the oven. Bake it for 30-40 min. Flip the peppers and onion half way into roasting.
Meanwhile in a medium mixing bowl combine mixed salmon, shredded zucchini, breadcrumbs, paprika, egg white, salt and pepper. Divide the mixture into six equal parts and form them into patties.
Heat oil in a large iron skillet on a medium heat. Cook the prepared patties for 3-4 min on each side or until well done.
Now, peel the roasted red peppers and remove all seeds and the core. Peel roasted onions and garlic as well.
In a food processor (or blender) add roasted red pepper, onion, garlic, basil, salt and pepper and pulse until well combined.
Now it is time to assemble the burger. On one side of the burger bun, place few leaves of arugula followed by cooked salmon patty, tomato slice, and onion slice. Finally, top with prepared roasted red pepper sauce. Enjoy this healthy salmon burger with your choice of sides
