Preheat Oven:
Preheat oven to 400°F (205°C). Cover a baking sheet with parchment paper.Prepare Dough Strips:
Unfold puff pastry (or unroll crescent dough). If using crescent dough, press seams together to create a single sheet. Slice dough into strips 1 to 1.5 inches (2.5-4 cm) wide.Assemble Rolls:
Optionally, brush a thin layer of Dijon mustard or mayo onto each strip. Place a ham slice on the strip, then set cheese at one end. Roll up like a sleeping bag, tucking the ends inward.Add Toppings:
Coat tops with egg wash for gloss and color. Dust with garlic powder, Italian seasoning, black pepper, and/or sesame seeds or grated Parmesan as desired.Bake Until Golden:
Bake 12 to 16 minutes until deeply golden and crisp.Cool Before Serving:
Allow to cool several minutes before serving since the cheese will be extremely hot.
