Ingredients

2 teaspoons honey

4 teaspoons Dijon mustard

3 tablespoons Champagne or white-wine vinegar

1/2 cup olive oil

Salt and pepper

1 medium yellow onion, thinly sliced lengthwise

1 cup fresh breadcrumbs

1 pound boneless, skinless salmon fillet, cut into 4 pieces

1 pound green beans, trimmed

Preparation

Preheat oven to 450 degrees. Whisk together honey, mustard, vinegar, and oil; season with salt and pepper. On a rimmed baking sheet, toss onion with 2 tablespoons vinaigrette and bake 5 minutes.

Meanwhile, stir 1 tablespoon vinaigrette into breadcrumbs. Coat fish with 1 tablespoon vinaigrette and season with salt and pepper; top with breadcrumb mixture and add to sheet. Bake until fish is cooked through, about 7 minutes.

In boiling salted water, cook green beans until crisp-tender, about 4 minutes; drain and toss with onion and 1 tablespoon vinaigrette. Refrigerate remaining vinaigrette in an airtight container for Chicken and Roasted Vegetable Salad. Serve fish with vegetables.
