1Preheat oven to 375°. Spray 8 inch round pizza pan with cooking spray.
2In a small bowl, combine mayo, mustard, parsley and onion. Mix well. Add chicken, bacon, parlsey, onions and most of the cheese, saving some for the top, if you choose to, if not add all the cheese. Mix well.
3Open crescent rolls and unroll dough. Separate dough into triangles and arrange them in a circle with the wide ends in the center of the baking pan. Spoon chicken mixture evenly onto the wide ends. Wrap pointed end around chicken mixture and tuck in the narrow ends. Place sliced Roma tomato wedge between the open parts. Bake 20 - 25 minutes until golden brown. Sprinkle with remaining cheese. I use Parmesean. NOTE: This recipe is easily doubled, just use a larger pizza pan.
