Southwest Steak & Potatoes

Directions

1. Pierce potatoes; place on a microwave-safe plate. Microwave, uncovered, on high 4-5 minutes or until almost tender, turning once. Cool slightly.
2. Meanwhile, mix vinegar and Worcestershire sauce; brush over steak. Mix brown sugar, chili powder, cumin, garlic powder, 1/2 teaspoon salt and cayenne until blended; sprinkle over both sides of steak.
3. Cut potatoes into 1/2-in. slices. Sprinkle with pepper and remaining salt. Grill potatoes and steak, covered, over medium heat 12-17 minutes or until potatoes are tender and a thermometer inserted in beef reads 145° for medium-rare, turning occasionally.
4. Cut steak into thin slices. Serve with potatoes.
