In a medium saucepan, combine beef broth, Worcestershire sauce, soy sauce, onion powder, garlic powder, salt, and pepper. Bring to a gentle simmer for 10-15 minutes.

In a separate skillet, gently reheat the thinly sliced roast beef over low heat for about 5 minutes.

Lay a flour tortilla flat, layer warm roast beef and shredded cheese, then roll up tightly and place seam-side down on a plate.

In a small bowl, melt butter and mix in garlic powder, onion powder, and dried parsley. Brush the roll-ups with this butter mixture.

Pan-fry or bake roll ups. For pan-frying, simmer for 2-3 minutes per side until golden brown, or bake at 375°F for 10-15 minutes.

Slice the cooked roll-ups into pinwheels for easy serving and arrange on a platter.
