Inspired by the ingredients for a traditional Spanish green gazpacho, this refreshing salad is served with a sherry, parsley, and tarragon dressing.
Preheat oven to 350 degrees. Place nuts on a rimmed baking sheet and bread cubes on a baking sheet; toast until nuts are aromatic and bread is dried and barely golden, about 7 minutes; set aside.
In a large bowl, combine tomato, pepper, cucumber, celery, red onion, scallions, grapes, parsley, tarragon, half the almonds, and the bread cubes. Drizzle with olive oil and vinegar. Add the salt and pepper. Toss well to combine. Let sit for 30 minutes for flavors to blend. Serve over lettuce garnished with remaining almonds.
