For Pumkin Rolls:

Defrost bread dough according to package directions.
Brush the cavities of Wilton Dimensions Multi-Cavity Mini Pumpkins pan with melted butter. Cut each loaf into 8 equal pieces; shape into rolls. Place rolls, seam side up, in each cavity. Cover loosely with plastic wrap; leave in warm place until doubled in size (about 45 minutes).
Preheat oven to 350°F. Remove plastic wrap from dough. Bake 24 to 26 minutes, or until tops are golden brown. Cool in pan 10 minutes; remove from pan and cool completely.

Flank Steak:

In shallow glass dish, combine olive oil, red wine vinegar, garlic, Worcestershire sauce, salt, thyme, mustard and pepper; whisk to combine. Add steak and turn to coat evenly. Cover and refrigerate 4 hours or overnight, turning steak occasionally.
Preheat broiler to high. Prepare broiler pan with vegetable pan spray. Remove steak from marinade; broil 6 minutes on each side for medium rare. Cover steak with foil and rest 5 minutes. To make bite-size pieces, cut steak into four strips with the grain; cut strips against the grain into smaller pieces.
Cut pumpkin rolls in half, fill with steak and favorite condiments, and serve.
