Preheat oven to 375°F (190°C).

In a small bowl, combine grated cheddar cheese, chopped ham, and finely chopped scallions.

Roll out crescent dough onto a flat surface.

Carefully divide the dough into the precut triangle shapes.

Add a heaping tablespoon of the ham mixture to the center of one of the triangles.

Roll up the dough triangle, starting at the narrow end.

Place the rolled turnover on a cookie sheet.

Repeat with the remaining ingredients.

If desired, brush the tops with milk.

Sprinkle lightly with an herb blend, paprika, or Parmesan cheese (optional).

Bake for 11 to 13 minutes, or until golden brown.

Let cool slightly before serving.
