Preheat oven to 375°. Unroll crescent dough and separate into 8 triangles; cut each lengthwise into 3 thin triangles. On the wide end of each triangle, place 1 slice apple, 1 folded piece cheese and 1 sausage; roll up tightly.
Place 1 in. Apart on parchment-lined baking sheets, point side down. Bake until golden brown, 10-12 minutes. If desired, serve with dressing.
