A recipe for Minute Steak may also be known as Swiss or Cube Steak.
Serve as is or over a bed of rice or noodles sprinkle with parsley. Side bar….I would opt for noodles buttered tossed with parmesan cheese and maybe some hot sauce because you will need help making this go down.
That said I think with a little tweaking this could become a delightful meal by adding mushrooms to the onions and leave out the vinegar . We did not cook this in a cast iron pan but I may try that also and brown the onions a little more for a more carmel color and sweet flavor.
