Spinach & Feta Stuffed Flank Steak Recipe

Starting at one long side, cut steak horizontally in half to within 1/2 in. of opposite side. Open steak flat; cover with plastic wrap. Pound with a meat mallet to 1/2-in. thickness. Remove plastic. Sprinkle 1 cup cheese over steak to within 1 in. of edges. Layer with spinach, tomatoes, onion and remaining cheese. Roll up jelly-roll style, starting with a long side; tie at 1-1/2 in. intervals with kitchen string. Sprinkle with 2 tablespoons flour, salt and pepper. In a large skillet, heat oil over medium heat. Brown beef on all sides; drain. Transfer to a 6-qt. oval slow cooker. In a small bowl, mix broth, Worcestershire sauce and tomato paste; pour over top. Cook, covered, on low 6-8 hours or until meat is tender. Remove beef to a platter; keep warm. Transfer cooking juices to a small saucepan; skim fat. Bring juices to a boil. Mix remaining flour and wine until smooth; gradually stir into pan. Return to a boil; cook and stir 1-2 minutes or until thickened. Serve beef with gravy and, if desired, noodles.
