Trim fat from meat and cut, if necessary, to fit into a 3 to 6-quart crockpot. In large skillet, brown meat on all sides, about 5-10 minutes. Place onions in crockpot and top with beef. Pour broth over all. Cover and cook on low for 8-9 hours or on high for 4-4-1/2 hours, until meat is tender. Remove meat from slow cooker, cover and let stand 10-15 minutes. Remove onions from crockpot. Split and toast the hoagie buns.
