Lightly oil a baking sheet or coat it with nonstick spray. Turn dough out onto a lightly floured surface and knead several times. Divide dough into 3 equal pieces. Roll each piece into an 18-inch rope, tapering the ends. Braid dough, pinching the ends together and tucking them under the loaf slightly. Transfer the loaf to prepared baking sheet. Cover loosely with plastic wrap and let rise in a warm place until doubled in bulk, about 45 minutes.
