Steak Burritos

Cut steaks in half; rub with taco seasoning. Place in a slow cooker coated with nonstick cooking spray. Top with onion, chilies and vinegar. Cover and cook on low for 8-9 hours or until meat is tender. Remove steaks and cool slightly; shred meat with two forks. (Turn to page 51 for a tip on shredding meat.) Return to slow cooker; heat through. Spoon about 1/2 cup meat mixture down the center of each tortilla. Top with cheese, tomato and sour cream. Fold ends and sides over filling.
