Citrus-Glazed Salmon with Spinach Salad
1 large ruby red grapefruit
12 to 16 ounces fresh spinach
3/4 cup white balsamic vinegar (or white wine vinegar with a touch of honey)
3 tablespoons olive oil
1/4 teaspoon salt
Freshly ground pepper
4 salmon fillets or steaks, about 4 ounces each
1 medium shallot, finely chopped
Peel and section grapefruit over a bowl, catching the juice; you’ll need about 1/4 cup. Dice grapefruit segments; place segments and spinach in a large bowl.
Combine 2 tablespoons grapefruit juice, 1/2 cup balsamic vinegar, 2 tablespoons olive oil, salt and pepper to taste in a small bowl. Arrange salmon on a plate; pour 1/2 cup vinaigrette over salmon (reserving remaining vinaigrette). Let stand 15-20 minutes.
Meanwhile, heat broiler. Line a broiler pan or shallow baking pan with foil; brush with oil. Remove salmon from marinade, discarding marinade; place salmon in pan. Broil 8 to 10 minutes.
To dress spinach, put reserved vinaigrette in a heavy saucepan; reduce slightly over medium-high heat. Mix remaining 2 tablespoons grapefruit juice, 1/4 cup vinegar and 1 tablespoon oil in a bowl with the shallots and reduced vinaigrette. Pour over spinach; toss to coat. Divide spinach among four dinner plates; top with salmon.
