One of my favorite meals as a kid, I now make this for my family. It is easy to throw together, and tastes great!
Combine the stew meat, mushroom soup, mushrooms with their liquid, and onion soup mix in the crock of a slow cooker. Pour in red wine, if desired. Season with pepper.
Cook on Low for 8 to 10 hours, or on High for 4 to 6 hours.
In the last half hour of cooking time, bring the rice and water to a boil in a saucepan over high heat. Reduce heat to medium-low, cover, and simmer until the rice is tender, and the liquid has been absorbed, 20 to 25 minutes.
