Thaw puff pastry sheets (about 40 minutes) until softened. Preheat oven to 375°F. Coat two baking sheets with spray.
Roll pastry sheets out into 10- x 13-inch rectangle. Brush with egg; top both with ham, then cheese slices, leaving a 1/2-inch border on the longer sides. Carefully roll the dough, starting with 1 long side, tightly around the filling; pinch seam together.
Cut each roll, seam-side down, using a serrated knife, into 12 slices (about 1-inch-thick); arrange pinwheels, cut-side up, on baking sheets. Combine remaining ingredients (except sesame seeds) in saucepan on medium; cook 1–2 minutes, stirring occasionally, or until hot.
Spoon mixture evenly over pinwheels; sprinkle with sesame seeds. Bake 20–25 minutes or until golden. Let stand 5 minutes to cool. Serve.
