Ramsay revealed the news to his almost 7 million followers on Twitter, posting a video of the dish,which appears to feature a vegetable wellington alongside roast potatoes, braised carrots, vegetables, and gravy, Ramsay wrote: "It's happened....the vegan roast has landed at Bread Street Kitchen."
Morgan retweeted the dish to his followers, saying: "Oh FFS, Ramsay... not you as well? This looks utterly revolting."
Morgan, who is well-known for lashing out at vegans - earlier this year, he pretended to be sick after tasting the new Greggs vegan sausage roll - ruffled some feathers with his tweet.
"Why, exactly, do you find the provision of vegan options, which you are in no way compelled to eat, so threatening?" asked one Twitter user. "Why would you deny others a choice which has zero impact on you? Or is this just posturing for rabble-rousing?"
"SHOCK: Piers Morgan shuts-down anyone else's choices or decisions that don't align with his own," another added.

Others took a different perspective, with one suggesting Morgan was using his platform to help create buzz around the product, with one commentator saying: "He's helping a mate promote his product. Just look at Greggs vegan [sausage] roll after he kicked up a fuss."
Another extrapolated something more meaningful from the Tweet, saying: "I don't think it's that he doesn't want anybody else to eat it, his problem is that SOME of the vegan community often have double standards. His points are often valid...The delivery often comes off as a rant but the context is always there."
And one user hated the dish simply because of the v-word, stating: "Looked great until I read vegan."
