Cut prosciutto vertically in half. Lay a spinach leaf on the prosciutto to almost cover. You will want about 1/4 edge of prosciutto free. If you need to use more than 1 spinach leaf overlap them to fit the prosciutto leaving a 1/4 inch edge. This will be the outside edge.

Add 1/4" of cheese cut in the shape of a matchstick to the inside edge. Add 1/4 tsp of antipasto toward the top of the spinach leaf. If using salad dressing a few drops is enough.

Starting at the stem edge of the spinach, roll the prosciutto up on a bit of an angle so it makes a sort of floral shape. Smooth the outside prosciutto edge to the back of the roll to seal it together.

Refrigerate until ready to serve. Can be made a few hours ahead.
