Ingredients

2 tablespoons dry mustard

3 tablespoons packed light-brown sugar

1/2 teaspoon soy sauce

1 tablespoon olive oil

4 salmon fillets, about 6 ounces each

Salt and freshly ground black pepper

1/2 bunch arugula, leaves slightly wet

4 slices sourdough bread, crusts trimmed

Preparation

Combine mustard and sugar in a small bowl. Stir in 1 1/2 tablespoons water. Add soy sauce and 1 teaspoon oil. Set aside.

Heat a grill or grill pan until very hot. Brush salmon with remaining oil; season with salt and pepper. Grill for 5 minutes, or until browned. Turn and cook for another 5 minutes, or to desired doneness.

Toast bread and place on plates. Top each with wilted arugula and a salmon fillet. Drizzle mustard sauce over top. Serve immediately.
