Heat large nonstick skillet over medium heat until hot. Add ground beef; cook 8 to 10 minutes, breaking into 3/4-inch crumbles and stirring occasionally. Pour off drippings.
Stir in potatoes. Cook 5 minutes, stirring occasionally. Stir in salsa and chilies; continue cooking 8 to 10 minutes or until potatoes are lightly browned, stirring occasionally. Sprinkle with cheese. Let stand 5 minutes.
Cook's Tip: Cooking times are for fresh or thoroughly thawed ground beef. Ground beef should be cooked to an internal temperature of 160°F. Color is not a reliable indicator of ground beef doneness.
