Grapefruit and orange transform a green salad into a refreshing dish worthy of your holiday table.
Working over a bowl, cut out grapefruit and orange segments, then squeeze 1/4 cup juice total from membranes.
Place endive and romaine and butter lettuces on a platter and top with citrus segments and onion. Whisk together citrus juices, yogurt, and oil. Drizzle over salad and season with salt and pepper.
If serving this for a kosher Hanukkah meal, replace the yogurt with 2 tablespoons red-wine vinegar.
