1 lb. ground beef
1 lb. Velveeta cheese, cubed
1 (10 oz.) can diced tomatoes and green chilies (drain off liquid)
2 tsp. Worcestershire sauce
1/2 tsp. chili powder

Brown ground beef and drain. Stir in all other ingredients and heat until cheese is melted. Serve with tortilla chips. Dip is good to put in crock-pot to keep warm while serving.
