Ingredients

4 ripe avocados

1/2 cup freshly squeezed lime juice (about 3 limes)

4 ruby-red grapefruits

1 tablespoon honey

1/2 cup extra-virgin olive oil

1/2 teaspoon crushed red-pepper flakes

Salt and freshly ground black pepper

3 heads red-leaf lettuce (2 pounds)

Preparation

Cut avocados in half lengthwise, working around pit; twist to open. Remove pits; peel. Cut avocados into 1-inch pieces; toss in bowl with 1/4 cup lime juice.

Using a sharp knife, cut away peel, pith, and outer membranes from grapefruits. Slice flesh crosswise into 1/4-inch-thick rounds; place in bowl.

Make vinaigrette: Combine remaining 1/4 cup lime juice and honey in small bowl. Whisk in olive oil and red-pepper flakes; season with salt and pepper.

Place lettuce in serving bowl. Season with salt and pepper; drizzle with a quarter of the vinaigrette. Toss well.

Drizzle avocado pieces with three-quarters of remaining vinaigrette. Season with salt and pepper; toss well. Scatter avocado and grapefruit slices over greens; drizzle salad with remaining vinaigrette.
