High street bakery Greggs has announced it will be selling a vegan-friendly sausage roll from 3 January. Instead of meat, the flaky pastry has a Quorn filling.

The vegan alternative will cost £1 – the same price as the bakery chain’s pork-filled sausage rolls.

Greggs have also confirmed the puff pastry used for the roll will be made without using butter, eggs or milk powder. Although it’s not yet known how many calories the vegan pastry contains, a pork-filled sausage roll contains 327 calories and 22g of fat.

The meat-free version of Greggs’ most famous menu item comes after 20,000 people signed a petition by the international animal rights group PETA (People for the Ethical Treatment of Animals) for an alternative to the classic pork snack last year. It was then trialled in a small number of stores.

Greggs are reported to sell 1.5million meat sausage rolls every week in the UK, but with 3.5million vegans living in the UK to new product should be popular.

Roger Whiteside, chief executive at Greggs, said: “Like many food retailers we have seen increasing demand for vegetarian and vegan products. We have been trying to develop a vegan version of our famous sausage roll for some time now.

“It has not been easy but our taste panel customers all love this one, so we have decided to launch it as our contribution to Veganuary.”

A spokesperson for Greggs on Bangor High Street confirmed the vegan sausage roll should be available in Bangor later this week.
