In a large nonstick skillet over medium heat, cook the turkey, onion and garlic in oil until meat is no longer pink. Stir in the tomatoes, salt and pepper; cook for 3-4 minutes or until tomatoes are tender. Remove from the heat; stir in cilantro.
Divide romaine among four plates; top each with 3/4 cup turkey mixture, 2 tablespoons cheese and 2 tablespoons salsa.
