Preheat oven to 375. Use pastry sheet as is. Do not roll or stretch. With a sharp knife, cut into 25 2×2â€ squares. Place each square on an oiled or parchment lined baking sheet. Brush each square with egg wash. Place a mini hot dog on each square and fold pastry around sausage. Do not wrap completely (encase like a taco). Repeat for each hot dog. Bake for 10-15 minutes, or until puff pastry is golden. Serve with mustard and catsup.
