Salisbury Steak..ever wonder?

Ever wonder what it is?

Here's a couple clues, Was invented by a Physician, Dr. J.H.Salisbury.

What is it made of...Well...What isn't it made of would be more to the point. It has to be 65% meat, of which up to 25% can be pork, except if defatted beef or pork is used, the limit then is 12% Combined. So we have a "sort of" meat substance combined into a steakish shape which are made up of 65% meat and 35% .... Something else.

Mmmm..
