Snap off tough ends of asparagus spears. Remove scales from spears with a knife or vegetable peeler, if desired. Arrange asparagus in a steamer basket over boiling water. Cover and steam 4 minutes or until asparagus is crisp-tender.
Place asparagus in a shallow dish; add tomato and remaining ingredients, and toss gently. Serve immediately, or cover and chill thoroughly.
