03Add wine to rice and onions, stir and cook just until it is absorbed. Start adding warm stock, about 1/2 cup at a time, stirring and adding more as it is absorbed. When 3 cups of the stock have been used, fold in tomatoes and sage. Season with salt and pepper. Risotto should be almost al dente. Continue cooking about 5 minutes more, adding a little more stock or some water if needed until rice is just done. Divide among 4 to 6 warm plates, top each with cheese and serve.
