Preheat your oven to the directions on your crescent roll can.
On a lined sheet tray, unroll your crescent dough and separate the triangles. Fold one piece of ham up into a square and place it on the triangle. Fold 1 piece of cheese into a small square to place on top of ham.
Wrap the ham pocket up like a present. Start by folding in the wings and start from the bottom of the triangle to fold up and wrap the tail of the dough. Optional to sprinkle poppy seeds on the dough.
