Oak leaf and baby romaine lettuces are so tender they’re best eaten straight from the garden or at least within a day or two of picking. Mild and delicate, they pair wonderfully with peppery radishes and chopped hard-boiled eggs in this easy salad.
- To prepare vinaigrette: Puree cucumber, oil, vinegar, chives, parsley, yogurt, mustard, horseradish, sugar and 1/2 teaspoon salt in a blender until smooth.
- To prepare salad: Season a wooden salad bowl by rubbing with garlic and pinch of salt. Chop the garlic and add to the bowl along with all the lettuce. Pour 1/4 cup of the vinaigrette over the greens; toss to coat. (Cover and refrigerate the remaining 1 cup vinaigrette for up to 3 days.) Serve the salad garnished with radishes, scallions and hard-boiled egg.
