1. Heat olive oil in a large skillet over medium high heat. Add the onion and garlic and cook, until tender, about 5 minutes. Add the green beans, water, basil, salt, and pepper. Cook, covered, over medium heat until beans are tender, about 10 minutes. (The cooking time will vary according to the size of the beans.)

2. Drain off any remaining liquid and stir 2 tablespoons cheese and optional sun-dried tomatoes into the beans. Spoon into a serving dish and sprinkle with remaining cheese.
