As much as I love a sandwich stuffed with a million different elements, it's sometimes nice to have a simple sandwich, one that highlights the flavors of a single star ingredient. For tonight's dinner why not make that sort of sandwich with a luscious piece of salmon as the starring flavor? The salmon is quickly grilled or pan-fried and topped with a mustard soy sauce. Arugula adds a peppery crunch, but if you don't like the taste of this leafy green, substitute spinach. To get the recipe to this sandwich that comes together in minutes,

Grilled Salmon Sandwich
From Martha Stewart

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 sourdough bread, crusts trimmed

  1. Combine mustard and sugar in a small bowl. Stir in 1 1/2 tablespoons water. Add soy sauce and 1 teaspoon oil. Set aside.
  2. Heat a grill or grill pan until very hot.
  3. 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.
  4. Toast bread and place on plates. Top each with wilted arugula and a salmon fillet. Drizzle mustard sauce over top. Serve immediately.
