Combine all ingredients, except celery, in a blender; blend to desired chunkiness. Cover and refrigerate. Serve chilled in bowls with celery as garnish.
For best results, coarsely chop veggies before blending. To loosen tomato skin, carefully pour boiling water over the top of tomato, then rinse in cold water. Skin can then be removed easily by hand.
