McCalister's Deli Spud Olé

6 medium baking potatoes
1 pound ground beef
2 tablespoons chopped onion
1/3 cup sour cream
1 can (4 ounces) chopped green chiles
3 tablespoons butter
1 tablespoon Worcestershire sauce
1 teaspoon salt
1/2 teaspoon garlic powder
1/2 teaspoon chili powder
3/4 cup shredded cheddar cheese
Chopped chives, optional

Bake potatoes at 375° for 1 hour or until tender. Cool. Meanwhile, in a large skillet, cook beef and onion over medium heat until beef is no longer pink, 6-8 minutes, breaking into crumbles; drain.
Cut a thin slice off the top of each potato. Carefully scoop out pulp, leaving a thin shell; place pulp in a bowl. Add sour cream, chiles, butter, Worcestershire sauce, salt, garlic powder and chili powder; mash or beat. Stir in meat mixture until combined. Stuff into potato shells.
Place filled potatoes on an ungreased baking sheet. Sprinkle with cheese. Bake at 350° for 10-15 minutes or until heated through. If desired, serve with sour cream and chives.
