I found this on an A-1 Steak Sauce bottle about 20 years ago. It called for 8 oz can of stewed tomatoes mixed with remaining A-1 Steak sauce to be put on top but I omit this and just add all of the A-1 into the meatloaf.
Mix beef with steak sauce, bread crumbs, and onions. On waxed paper, pat to a 12x8 ", top with cheese and broccoli. (Keep a small ball of meat mixture to fix any cracks in the rolled up meat loaf). Roll up from the short end; seal. Transfer to a baking pan with sides. Seal any cracks that happen while transferring to dish. Bake at 350 degrees for 1 hour.
