Risotto makes a great side dish. It's creamy, but not overly rich. It has a little bit of a bite, but not crunchy and not mushy. Once you get the hang of cooking it, you can add all sorts of ingredients. The possibilities are endless.
Bring the stock to a boil in a pan, then reduce the heat and keep simmering gently over low heat while you are cooking the risotto.
Heat the oil in a deep pan. Add the rice and cook over low heat, stirring constantly, for 2-3 minutes, until the grains are thoroughly coated in oil and translucent.
Add the garlic, onion, celery, and bell pepper and cook, stirring frequently, for 5 minutes. Add the mushrooms and cook for 3-4 minutes. Stir in the oregano.
Gradually add the hot stock, a ladeful at a time. Stir constantly and add more liquid as the rice absorbs each addition. Increase the heat to medium so that the liquid bubbles. Cook for 20 minutes, or until all the liquid is absorbed and the rice is creamy.
Add the sun-dried tomatoes 5 minutes before the end of cooking time and season to taste with salt and pepper.
Remove the risotto from the heat and stir in the Parmesan until it melts. Ready to serve!
