CROCKPOT ROULADEN

Steps:

• Cut steak into 6 equal portions. Place each piece between two layers of plastic wrap and pound with a mallet or rolling pin until about 1/4" thick. Spread each piece with mustard and set aside. Place carrots in bottom of 5-6 qt slow cooker.
• Cook bacon in skillet until crisp. Drain on paper towels. Meanwhile, in bacon grease left in skillet, saute onions until tender, about 5 minutes. Remove onion to a bowl with slotted spoon. Add chopped pickles. Crumble bacon and add to onion mixture. Divide equally amongst pieces of beef; roll each piece around the filling and secure with kitchen twine. Dredge in flour, tapping off any excess.
• Add butter to any remaining bacon grease. When foaming subsides, add beef rolls and brown 1-2 minutes on each side. As each is finished, transfer to the slow cooker on top of the carrots. Pour beef stock over all. Cover and cook on low 6-7 hours until carrots are tender and beef is very tender. Remove beef with tongs; carefully remove strings. Remove carrots with a slotted spoon.
• Combine sour cream and flour; stir well. Add to liquid remaining in slow cooker and stir well. Turn heat to high. Return beef and carrots to pot and cover. Cook 10-20 minutes until thick. Season with salt and pepper to taste. Serve hot.
