Rather than sausage, the new roll will be filled with Quorn, a meat substitute, and wrapped in 96 layers of dairy-free puff pastry.
It is now available in 950 selected stores in the United Kingdom starting today and only costs £1.
"Everyone tag Piers Morgan in it to ruin his day", the chain pizza restaurant tweeted Thursday, tagging the Twitter page of Greggs - a United Kingdom bakery that had just been involved in a Twitter squabble with Morgan the day earlier.
The launch follows strong consumer demand, including a petition by PETA past year, which was signed by more than 20,000 people. The company sells 1.5m traditional pork sausage rolls a week.

The government has also ramped up spending on infrastructure to rekindle sluggish demand and investment. The reduction is being made in two equal stages, effective January 15 and January 25, the PBOC said.
"Like our pals at the sausage roll place, we've been expecting you", replied McDonald's.
The product arrives on Greggs's shelves at the start of Veganuary - a growing movement that encourages people to embrace plant-based diets during January.
Like manna from heaven, the greatest gift 2019 has proffered so far is the Greggs vegan sausage roll.
Vegans will be left disappointed as one of the only Greggs stores to sell the new vegan sausage rolls have not received their delivery.
"It has not been easy but our taste panel customers all love this one, so we have made a decision to launch it as our contribution to Veganuary".
