easy salmon cakes with arugula salad

Directions:

1. Coarsely chop salmon and place half in a food processor. Add 1 tablespoon lemon juice and 1 teaspoon mustard. Process, scraping down the sides as necessary, until smooth. Add the remaining salmon, bell pepper, shallot and 1/4 teaspoon pepper and pulse until the mixture is combined but still chunky.
2. Transfer the salmon mixture to a medium bowl. Add breadcrumbs and stir until combined. Form the salmon into 4 patties, about 4 inches wide each, and place on a plate. Freeze for 5 minutes.
3. Meanwhile, whisk crème fraîche (or sour cream), buttermilk, dill and 1/4 teaspoon salt with the remaining 1 tablespoon lemon juice, 1 teaspoon mustard and 1/4 teaspoon pepper in a large bowl. Set aside 1/4 cup of the dressing for drizzling.
4. Heat oil in a large cast-iron or nonstick skillet over medium-high heat. Add the salmon cakes and cook, flipping once, until well browned and cooked through, 2 to 3 minutes per side. Transfer to a clean plate and sprinkle with the remaining 1/4 teaspoon salt.
5. Add arugula and radishes to the dressing in the large bowl. Toss to coat. Serve the salmon cakes on top of the salad, drizzled with the reserved 1/4 cup dressing.
