Preheat oven to 375 degrees F (190 degrees C).
Separate Crescent Roll Dough (8 ounce) into 8 triangles. Cut each into 3 triangles.
Place Vienna Sausages (18.4 ounce) over wide end of triangle, and roll up. Reshape dough a little, if necessary, and stick a toothpick through the middle to maintain the shape. Arrange on ungreased cookie sheet or baking pan.
Bake in the preheated oven for about 10 minutes, or until golden brown.
Serve immediately with Yellow Mustard (8 ounce). Enjoy!
