Simple French Dip Sandwiches

Trim fat from meat. In a large skillet, brown roast on all sides in hot oil; drain off fat.

Place onions in a 5- to 6-quart slow cooker. Place meat on top of onions. In a bowl, whisk together broth, gravy mix, and pepper. Pour over meat in cooker.

Cover; cook on low-heat setting for 10 to 11 hours or on high-heat setting for 5 to 5 1/2 hours. Transfer meat to a cutting board. Slice meat across the grain and return to cooker to keep warm. With a slotted spoon, remove meat and onions and serve on hoagie buns. Serve with bowls of cooking juices for dipping.
