2 cups water
1 cup rice
1 pound sirloin steak, sliced
1 tablespoon vegetable oil
8 ounces mushrooms, sliced
1 onion, peeled and sliced
1/4 cup water
2 tablespoons all-purpose flour
1 teaspoon dry mustard
1 teaspoon salt
1/4 teaspoon ground black pepper
1 cup sour cream
Combine water and rice, cover, and microwave on HIGH for 10 minutes. Continue cooking during meat preparation or until liquid is absorbed and rice is tender.
In a microwave-safe bowl, combine meat with oil and toss to evenly coat. Cover and microwave on HIGH for 5 minutes.
Remove meat from bowl and set aside. Add mushrooms and onion. Cover and microwave until mushrooms are tender, about 5 minutes.
Combine water and flour; stir into mushroom mixture. Sprinkle with dry mustard, salt and pepper. Microwave, uncovered, to boiling, about 30 seconds; then microwave until thick, about 1 minute.
Stir in meat, then sour cream. Microwave, uncovered, until hot, about 1 minute. Serve over rice.
