Try this simple meat and potatoes meal for a quick weeknight dinner.
Pierce potatoes with fork; place on paper towel in microwave. Microwave on HIGH (100% power) 7 minutes; turn potatoes over. Continue microwaving on HIGH until fork tender (8 to 10 minutes). Cover; let stand 5 minutes.
Meanwhile, in medium bowl stir together all remaining ingredients. Split hot potatoes in half; top each with about 1/4 cup beef mixture. Microwave on HIGH (100% power) until cheese begins to melt (1 to 2 minutes).
