How to Make It
Bring vinegar and sugar to a simmer in a small saucepan. Remove from heat; add onion, tossing to coat. Set aside.
Steam green beans, covered, 6 minutes or until crisp-tender.
While green beans cook, place roasted red bell pepper and next 5 ingredients in a food processor; process until smooth. Drain onion; discard vinegar mixture.
Rinse green beans under cold water; drain well. Combine green beans, onion, tomatoes, walnuts, and olives in a large bowl. Add bell pepper dressing; toss gently to coat. Serve warm, at room temperature, or chilled.
