Bloody Mary Green Bean Salad

Prepare Salad: Cook beans in boiling salted water to cover 2 minutes or until crisp-tender; drain. Plunge into ice water. Drain and pat dry. Place beans, onion, and okra in a large bowl. Place tomatoes, celery, and celery leaves in a separate bowl.

Prepare Dressing: Whisk together Bloody Mary mix, next 5 ingredients, and 4 tsp. horseradish in a medium bowl. Add oil in a slow, steady stream, whisking constantly until blended.

Toss bean mixture with 1/4 cup dressing; arrange on a platter. Stir remaining 1/2 tsp. horseradish into 1/4 cup dressing, and toss with tomato mixture. Spoon tomato mixture over bean mixture. Add salt and pepper to taste; serve with remaining dressing.
