Best French dip recipe I've ever tasted. Cooking in the crock pot is so convenient and worry-free! Also, using boneless chuck makes for just about the tenderest meat ever -however, check doneness after about 2 1/2 - 3 hours every half hour by sticking a fork into the meat. When the fork goes in easily practically all the way, it's done. If you overcook it, it looses all its tenderness. With fresh-baked rolls - to die for!
