Heat oven to 400°F. Spray 9-inch round pan with cooking spray. In medium bowl, mix cream cheese, Vejje chicken, hot sauce, and vegan Cheddar cheese until well blended.
On large cutting board, unroll dough sheet; spread Vejje chicken mixture evenly on dough to within 1/4 inch from sides. Starting with one long side, roll up dough; firmly pinch seam to seal.
Place seam side down on cutting board. Using sharp knife, cut roll into 8 equal slices; place cut side down in pan. Bake 25 to 30 minutes or until deep golden brown. Serve with ranch dressing and, if desired, additional Buffalo sauce.
