Ingredients

  • 1 1/2 pounds skinless salmon fillet, preferably center-cut
  • 4 tablespoons extra-virgin olive oil, divided
  • 1 teaspoon kosher salt
  • 1/2 teaspoon freshly ground black pepper
  • 1 small shallot, chopped
  • 2 tablespoons white wine vinegar
  • 4 ounces pitted Castelvetrano olives (about 1 cup)
  • Zest of 1 lemon (about 2 teaspoons)
  • 2 tablespoons lemon juice
  • 1/2 cup fresh parsley, roughly chopped
  • 1 1/2 tablespoons fresh oregano, roughly chopped
  • 1 pinch red pepper flakes
  • 4 Arnold®, Brownberry®, or Oroweat® Potato Sandwich Buns, toasted
  • 4–6 tablespoons mayonnaise
  • 1 1/2 cups romaine or iceberg lettuce, shredded

Directions

  • Preheat the oven to 300°F. Line a rimmed baking sheet with aluminum foil.
  • Place the salmon fillet on the baking sheet and drizzle with 1 tablespoon olive oil, rubbing it over both sides of the fillet so every surface is lightly coated. Season both sides with salt and pepper and place salmon on what would be the skin-side down. Roast until medium to well-done, depending on your preference, about 18 to 22 minutes for medium to medium-well, and 23 to 27 minutes for well-done. Remove from the oven, let cool for 15 minutes and then break into large pieces about 3 inches long.
  • While the salmon is roasting, start the relish by combining chopped shallots and white wine vinegar in a small bowl. Toss to coat the shallots in the vinegar and let sit for 15 minutes (this will mellow their oniony pungency).
  • Combine the macerated shallots with the remaining 3 tablespoons olive oil, olives, lemon zest, lemon juice, parsley, oregano, and red pepper flakes in a food processor. Pulse until a coarse, but uniform paste forms. Transfer to a bowl, then taste and season with salt, if necessary.
  • To assemble the sandwiches, spread a generous layer of mayonnaise on the bottom bun. Top with several pieces of slow-roasted salmon and a handful of shredded lettuce. Spread a thick layer of olive relish on the top bun, and place it on top of the lettuce and salmon, gently pressing it down. Repeat with the remaining sandwiches and serve immediately.
