In a large saucepan, saute onion in butter until tender.  Stir in flour until blended.  Gradually add broth & milk.  Bring to a boil; cook & stir for 2 minutes.  Remove from the heat; stir in cheese.  Pour 1/3 cup each into two greased 8" square baking dishes; set aside.

In a large bowl, combine 1 cup cheese sauce, chicken, broccoli, eggs, bread crumbs, pimientos, parsley & salt.  Spread about 1/2 cup over each noodle.  Roll up jelly roll style, beginning with a short side.  Secure ends with toothpicks.

Place 6 rollups curly end down  in each baking dish.  Top with remaining cheese sauce.  Freeze.
