Combine two rolls and roll into a 12-inch rope. Tie each rope into an overhand knot. Bring one end of the dough over the top and tuck down into the middle. Bring the other end of the dough through the center, going the opposite way.
Place on a large sprayed baking sheet. If desired, brush with egg and sprinkle with sesame seeds. Bake at 350°F 15-20 minutes.
