Ingredients

2 red grapefruit

3/4 teaspoon white-wine vinegar

1 tablespoon honey

1 1/2 tablespoons low-fat sour cream

1/8 teaspoon coarse salt

Freshly ground pepper

1 1/2 tablespoons extra-virgin olive oil

4 Belgian endives

1 ripe Hass avocado, pitted and peeled

Preparation

Cut peels, including pith, from grapefruit; discard. Working over a bowl to catch any juices, cut segments from membranes, letting them fall into bowl. Squeeze the remaining juice from membranes into bowl.

Whisk together vinegar, honey, sour cream, salt, and 3 tablespoons grapefruit juice in a small bowl. Season with pepper. While whisking, add oil in a slow steady stream; whisk until emulsified.

Halve endives lengthwise, and core; cut leaves into 1-inch-thick pieces. Toss with three-quarters of the dressing. Cut avocado into 1/4-inch-thick slices. Divide endive and avocado among four plates. Drizzle each serving with one-quarter of the remaining dressing. Divide grapefruit segments among plates.
