Question: what is inside greggs vegan sausage roll?
Answer: The Greggs vegan sausage roll is made of fungal mycoprotein instead of pork and features a paler pastry cylinder due to the absence of a fat-based glaze. ... The blend has been “exclusively” made for the bakery (presumably because Quorn isn't vegan) using mycoprotein, which is fermented fungus that grows in the ground.
