The recipe came from the book Crock Pot Slow Cooker Best-Loved Recipes.
Burgundy Beef Po' Boys with Dipping Sauce:
1 boneless beef chuck shoulder or bottom round roast (3 pounds) ~ we used rump roast
2 cups chopped onions
1/4 cup dry red wine
3 TB balsamic vinegar
1 TB beef bouillon granules
1 TB Worcestershire sauce
3/4 tsp dried thyme
1/2 tsp garlic powder
*Trim excess fat & discard. Cut beef into 3 or 4 pieces. Place onions on bottom of crock pot slow cooker. Top with beef and remaining ingredients. Cover and cook on HIGH 8 - 10 hours or until beef is very tender.
*Remove beef from crock pot, allow to cool slightly. Shred with 2 forks. Let cooking liquid stand 5 minutes to allow fat to rise. Skim off fat and discard. Spoon beef into Italian rolls. Serve the cooking liquid as dipping sauce.
We served it with some corn and with the roasted garlic bread on the side.
