On a lightly floured surface, roll dough to a 12x9-inch rectangle, stopping occasionally to let dough relax a few minutes for easier rolling. Spread sausage mixture evenly over dough, leaving a 1-inch border on all sides. Starting from a short side, roll up dough into a spiral. Moisten edge and ends; pinch seams to seal. Transfer to a lightly greased baking sheet. Cover and let rise in a warm place till nearly double (30 to 45 minutes).
