For those who have questioned how much meat is really in a meat pie, there's now one where you know for sure.

The pie company intends to start rolling out the vegetarian option to service stations, supermarkets and football grounds next month.

With a filling consisting mainly of soy protein, the meat-free pie is intended to smell and taste like the real thing.
