Preheat oven to 375 degrees F.
Cut each piece of dough into 2 and roll out until 1/4-inch thick. Cut 6 pieces of dough about 3 inches wide and 1/2-inch shorter then the length of sausage, just enough to wrap around sausage with the ends peeking out. Spread bottom of each dough with a tablespoon of garlic/mustard paste. Set sausage on top, moisten 1 dough edge with a wet finger so it sticks together and roll. Press the seam firmly and set them on a lightly floured sheet pan, seam side down. Brush with olive oil. Bake until brown all around.
Remove and let cool for 5 minutes. Cut into 3/4-inch long pieces and serve.
