Open up your crescent rolls keeping them in rectangles (pinch together the break lines). Spread about a teaspoon of raspberry preserves on top.
Add 2 slices of provolone cheese to each one.
Add a slice or two of ham.
Carefully roll them up.
Bake for 20-25 minutes in a 350 degree oven. Sprinkle with powdered sugar (optional), and allow to cool for a few minutes. Cut the roll-ups in half or even quarters before serving.
