Beef dips are one of our favorite meals when we have leftover beef.
Start with this, a large grilled tri-tip, or any cut of meat. Cook enough for leftovers. Refrigerate for a day or two. Cut leftover meat into thin slices.
Buy a package of Au Jus mix and combine it with water. Heat until hot.
Purchase some French Sandwich Rolls. Butter them, top and bottom, and broil just until lightly browned.
Dip sliced beef into Au Jus and lay on the bottom of the French roll. Cut each roll in half and serve with Au Jus for dipping.
Prepared Horseradish is also good mixed into the Au Jus for a little zip.
