Rich delicate salmon is combined with horseradish, lemon, and seasonings, then topped with a refreshing tangy yogurt-dill sauce to create these hearty, yet light Salmon Burgers. Super easy and delicious!
Heat broiler, with rack set 4 inches from heat. Coat a baking sheet with nonstick cooking spray.
With a sharp knife, slice salmon into very tiny cubes (about 1/8-1/4 inch.)
In a medium bowl, whisk together the horseradish, lemon juice, egg, scallions, breadcrumbs, salt, and pepper. Gently fold in the salmon.
Form salmon mixture into 4 equal portions, about 3 1/2 inches round and 1 inch thick. Place on the prepared baking sheet. Broil, without turning, until golden on top and opaque throughout, 6-7 minutes. (Watch them carefully so they don't burn.)
Slather buns with some Tzatziki sauce and top with arugula and a salmon burger.
