Place tuna on grill rack coated with cooking spray; grill 2 minutes on each side or until desired degree of doneness.
  • To prepare salad, place onion slices on grill rack coated with cooking spray; grill 5 minutes on each side or until tender. Cool and chop.
  • Combine vinegar and next 5 ingredients (through garlic) in a large bowl, stirring with a whisk until blended. Add onion, cucumber, parsley, capers, and beans to vinegar mixture; toss to coat. Arrange 1 1/2 cups salad greens on each of 4 plates. Top each serving with about 1/2 cup onion mixture and 1 tuna steak.
