Preheat oven to 375 degrees.
Coat one side of each flattened chicken piece with 1 teaspoon of oil then place one basil leaf on top of each piece.
In a small bowl, combine 1/2 cup of chopped sun-dried tomatoes with the Mozzarella cheese, rosemary, oregano, salt and pepper; spoon an equal amount of this mixture on top of each basil leaf then carefully roll each chicken piece around the basil leaf and filling; secure with toothpicks if necessary.
Place chicken rolls in a casserole dish, seam side down; drizzle with remaining oil. Bake until golden brown.
Garnish with remaining chopped sun-dried tomatoes and serve.
