Combine beans, tuna, bell pepper, onion, parsley, capers, rosemary, 1/4 cup lemon juice and 2 tablespoons oil in a medium bowl. Season with pepper. Combine the remaining 1/4 cup lemon juice, 2 tablespoons oil and salt in a large bowl. Add salad greens; toss to coat. Divide the greens among 4 plates. Top each with the tuna salad.
Tips
Note: Chunk light tuna, which comes from the smaller skipjack or yellowfin, has less mercury than canned white albacore tuna. The FDA/EPA advises that women who are or might become pregnant, nursing mothers and young children consume no more than 6 ounces of albacore a week; up to 12 ounces of canned light tuna is considered safe.
