  • Add butter to veggie mixture; cook until butter is melted. Sprinkle in flour; cook, stirring constantly, 1 to 2 minutes. Whisk in milk, Worcestershire, and dry mustard until smooth.

  • Reduce heat to medium-low, and stir in Velveeta until smooth. Remove from heat, and stir in cooked pasta, roast beef, and 1 1/4 cups provolone until combined.  

  • Pour mixture into an 11- x 7-inch baking dish lightly coated with cooking spray; top with remaining 3/4 cup cheese. Stir together panko and remaining 1 teaspoon oil in a small bowl. Sprinkle breadcrumb mixture evenly over pasta mixture, and bake in preheated oven until golden and bubbly, 20 to 25 minutes. Sprinkle with parsley, if desired.
