Grilled Salmon Fillet with Honey-Mustard Sauce
Whole-grain mustard and horseradish pack a punch in this salmon recipe.
Whisk together the mustards, honey, horseradish, mint and 1/4 teaspoon of salt and 1/4 teaspoon of pepper in a small bowl. Let sit for at least 15 minutes before using. Can be made 1 day in advance and refrigerated but do not add the mint until just before using. Bring to room temperature before using. Heat the grill to high. Brush the salmon with the oil and season with salt and pepper. Place the salmon on the grill, skin side down, and grill until golden brown and slightly charred, about 3 minutes. While the salmon is cooking, place the watercress and onion in a medium bowl, add the vinegar and oil and salt and pepper and toss to combine. Transfer the salad to a platter, top with the salmon fillet and drizzle each fillet with the mustard sauce.
