Roast Beef Waldorf Salad - cooking recipe

Ingredients

6 -8 ounces roast beef, rare and sliced (quality matters here, for this dish I go for rare, sliced RB from Whole Foods)
1 cup greens (field greens, about two small handfuls)
5 -6 sprigs fresh cilantro
2 stalks celery
1/4 cup red onion (4-5 thin slices)
1 small apple (Fiji is my choice for its sweet taste)
3 tablespoons low-fat mayonnaise
2 tablespoons low-fat yogurt
1 tablespoon horseradish (Bottled, white. Can often be found in the refrigerated section near the dairy products)
1/2 - 1 teaspoon lemon juice, fresh
1/4 cup dried fruit (i.e. raisins, dried cranberries, dates, etc.)
1/4 cup walnuts, chopped
1/4 teaspoon salt (about two dashes)
1/4 teaspoon pepper (about two dashes)

Preparation

Chop the sliced roast beef into 2-inch chunks.
Finely chop the cilantro and celery.
Cut 4-5 thin slices from the red onion.
Remove the apple's core and, skin intact, cut the apple into 1-inch pieces.
Squeeze 1/2-1 tsp juice from the lemon.
Combine all the ingredients in a medium bowl, stir/toss and serve.
Serves four as a small dish or serves two as a large dish.
