Creating French Dip Tortilla Roll Ups is straightforward if you follow these easy steps:

1. Prepare the Beef: In a skillet over medium heat, combine the sliced roast beef, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Cook until heated through, about 5 minutes.

2. Warm Tortillas: Heat the tortillas in a dry skillet or microwave for a few seconds until warm and pliable.

3. Assemble the Roll Ups: Lay a tortilla flat on a clean surface. Place a portion of the beef mixture in the center, then top with a generous sprinkle of provolone cheese.

4. Roll It Up: Carefully roll the tortilla tightly around the filling, ensuring the edges are tucked in as you go. Repeat this step for the remaining tortillas.

5. Cook the Roll Ups: Heat a skillet over medium heat. Place the roll-ups seam-side down in the skillet and cook until golden brown and crispy, about 3-4 minutes per side.

6. Prepare Au Jus: In a small saucepan, heat the beef broth until simmering. This will be your dipping sauce.

7. Slice the Roll Ups: Once cooked, remove the roll-ups from the skillet. Let them cool slightly before slicing them into bite-sized pieces.

8. Garnish: If desired, sprinkle chopped parsley over the top for an appealing presentation.
