Coarsely chop grilled tomatoes. In a medium bowl gently toss together tomatoes, the remaining 2 tablespoons lemon juice, the beans, the remaining 3 teaspoons oil, the garlic, the snipped rosemary, and 1/4 teaspoon salt. Divide bean mixture among four dinner plates. Place fish on bean mixture. Serve with lemon wedges. If desired, garnish with fresh rosemary sprigs.
