Brush corn with 1 tablespoon oil. Grill, covered, over medium heat 10-12 minutes or until lightly browned, turning occasionally. Grill tomato slices 1-2 minutes on each side or until lightly browned.
Cool corn slightly. Cut corn from cobs; transfer to a small bowl. Stir in green onion, parsley, olives, capers, garlic, lemon juice, lemon zest and remaining oil.
Serve corn mixture over tomatoes; sprinkle with cheese. If desired, serve with baguette slices.
