Preheat Oven: Set your oven to 375°F (190°C) and line a baking sheet with parchment paper.

Assemble Tortillas: Lay each tortilla flat on a clean surface. Fill each with a slice of roast beef and a generous handful of shredded cheese.

Roll Up Tortillas: Fold the sides of the tortilla in slightly and then roll from the bottom to the top tightly, placing seam-side down on the prepared baking sheet.

Brush and Season: Brush the tops of the roll ups with melted butter. Sprinkle with garlic powder, onion powder, and dried parsley.

Bake: Place the baking sheet in the oven and bake for 12-15 minutes.

Make Au Jus: In a saucepan, simmer together beef broth, Worcestershire sauce, soy sauce, garlic powder, onion powder, salt, and pepper over medium heat for 5-7 minutes.

Serve: Slice the roll-ups into bite-sized pieces and serve warm with the au jus on the side.
