This another of Mum’s recipes that she’s pinned together when she couldn’t find the cellotape. It was probably published before mayonnaise in all it’s different varieties was available in the supermarket. If you don’t want to go to the trouble of making the mayonnaise use about a cup of a plain bought one and add the mustard and parsley.
Instead of using mince steak this meatloaf uses minced lamb and it’s other unusual ingredient is a container of potato salad. Usually potato salad accompanies a meatloaf instead of being mixed in, but the potato and it’s mayonnaise dressing combined with the French onion soup mix make this a tasty change.
Potato Salad has been around for a long, long time, but I thought it interesting that Mum had this American Potato Salad in her collection. As far as I can see the main thing that is different from our home grown Australian versions is the dill pickles.
