Preheat oven to 350°F. Coat an 8×10-inch baking dish with nonstick cooking spray. Place chicken breasts in prepared dish. Cut 5 to 6 slits across, but not through, each chicken breast. Set aside.
Coat a large nonstick skillet with nonstick cooking spray. Place skillet over medium heat. Add spinach, tomatoes, garlic, Italian seasoning and 1 1/2 tablespoons water; sauté 2 minutes or until spinach wilts. Remove from heat; stir in cheese.
Fill slits in each chicken breast evenly with spinach mixture. Sprinkle chicken with freshly ground black pepper to taste. Bake 20 to 25 minutes or until an instant-read thermometer inserted into chicken registers 165°F. Serve warm with lemon wedges.
