Wash the rosemary, shake dry, pluck the needles from the twigs and chop roughly. Cut sausage into strips. Unroll the dough, place it on a floured work surface with the dough side down, remove baking paper.
Spread the rosemary and sausage on the dough, sprinkle lightly with salt. Cut the dough in half lengthwise with a pizza cutter and cut both halves into strips about 2 cm wide. Turn the strips into sticks and place them on 2 baking trays lined with baking paper.
Bake one after the other in a preheated oven (electric oven: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 7 minutes. Arrange the finished Grissini in glasses and garnish with rosemary.
