- 1 tablespoon Dijon mustard
- 1/4 cup freshly squeezed lemon juice
- 1 1/2 teaspoons kosher salt
- 3/4 teaspoon freshly ground black pepper
- 1/2 cup good olive oil
- 4 ripe Hass avocados
- 2 large red grapefruits
Before serving, cut the avocados in 1/2, remove the seeds, and carefully peel off the skin. Cut each half into 4 thick slices. Toss the avocado slices in the vinaigrette to prevent them from turning brown. Use a large, sharp knife to slice the peel off the grapefruits (be sure to remove all the white pith), then cut between the membranes to release the grapefruit segments.
