- 6 medium red or golden beets
 - Salt and pepper
 - 1 tablespoon red wine vinegar
 - Extra virgin olive oil
 - 1 large shallot, diced fine
 - 2 tablespoons white wine vinegar
 - 1 tablespoon lemon juice
 - 1 tablespoon orange juice
 - 1 tablespoon chopped chervil
 - ¼ teaspoon chopped lemon zest
 - ¼ teaspoon chopped orange zest
 - 2 firm, ripe avocados
 - Chervil sprigs
 
- Preheat the oven to 400°F.
 - Trim and wash the beets. Put them in a baking dish, add a splash of water, and cover tightly. Roast the beets in the oven for about 45 minutes, until they are cooked through.
 - When the beets are cooked, allow them to cool uncovered. Peel and cut them into wedges. Put them in a bowl, season generously with salt and pepper, add the red wine vinegar and 1 tablespoon of olive oil, and toss gently.
 - Put the shallot in a bowl and add the white wine vinegar, lemon juice, orange juice, and a pinch of salt. Let macerate for 15 minutes. Whisk in ¾ cup olive oil and stir in the chopped chervil, lemon zest, and orange zest. Taste for seasoning.
 - Cut the avocados in half lengthwise and remove the pits. Leaving the skin intact, cut the avocados lengthwise into ¼-inch slices. Scoop out the slices with a large spoon and arrange them on a platter or individual dishes. Season with salt and pepper. Arrange the beets over the avocado slices and drizzle with the vinaigrette. Garnish with a few chervil sprigs.
 - Variation: Blood orange, grapefruit, Meyer lemon, and kumquat go well with the roasted beets and citrus dressing—with or without the avocados—as do watercress and Belgian endive.
