How to Make It
Heat oven to 400° F. Cut the sausages in quarters lengthwise, then in half crosswise. Cut the puff pastry into strips 3 inches long and 1 inch wide.
Roll the sausage pieces in the pastry strips and transfer to a parchment-lined baking sheet. Bake until puffed and golden brown, 15 to 20 minutes. Serve with the mustard for dipping.
