Mix all spices, 1 egg, onion, and bread crumbs together with the ground beef.
Thaw puff pastry according to directions on box. Unroll 1 sheet and roll it out with a bit of flour into a rectangle. Cut the sheet into 3 equal rectangles.
Preheat oven to 400 degrees F.
Form ground beef into long kabobs or rolls that fit the length of the puff pastry. Using a pastry brush, brush the sides of each thin rectangle with water and pull up the edges to bring them together.
Crimp the edges with a fork and cut into 2 inch sized pieces with a sharp knife. Arrange on a parchment lined baking sheet.
Brush tops with a beaten egg and sprinkle sesame seeds on top, if desired. Bake in a preheated oven for 10 to 15 mins or until tops are golden and meat is cooked inside. Enjoy warm.
