This traditional Israeli salad makes a light and healthy side dish.
Combine red pepper, cucumber, arugula, tomatoes, and scallions in a large bowl. In a small bowl, combine the lemon juice, salt, black pepper, and zahtar. Use a fork to whisk in the olive oil. Drizzle over salad, and toss to combine.
Just before serving, toss in toasted pita. Sprinkle preserved lemons and crumbled feta, if desired, over salad.
Make the olive-cured olive oil by placing half a cup (2 and a half ounces) Moroccan or Kalamata olives in one cup of extra-virgin olive oil. Let steep for at least one day, and use as olive oil in salads, marinades, etc.
