Veganism has taken over the world in the past few years, as concerns about climate change and animal welfare push what we eat to the top of the agenda.
Now, every supermarket has a dedicated plant-based aisle and there are vegan versions of every food, from chorizo to king prawns to stir-fry chicken.
But though the public are increasingly ditching meat in favour of vegetables and replacement products like pea protein and tofu, one very famous cook isn't so keen.
Nigella Lawson tried going vegan for a fortnight recently, and concluded that she "doesn't see the point" in giving up animal products.

She added that while she likes vegetables and also respects the vegan viewpoint, it's not for her.
Nigella believes that "humans have the teeth for meat" and admitted she craved eggs within the fortnight, saying that without meat or dairy, she felt run-down.
"As far as I’m concerned I want to eat proper food," she said.
"I don’t want to lecture anyone because I feel, well, I cling to the thing that we have the teeth for meat and so it’s natural for us to want to eat it... it’s an argument that a lot of vegans disagree with… I respect that position but I feel that I’m not ready."
More in tune with the growing vegan vibe is Jamie Oliver. The famous chef has announced that he will reduce or "eliminate" meat in two-thirds of new recipes, in a bid to go carbon-neutral over the next 20 years.
His hugely popular recipes will still use some meat, but he also pledged to cut down the amount used in individual recipes such as spaghetti bolognese. However, he failed to set a deadline for changing his approach.
A spokesperson for The Vegan Society said: “While it’s hugely encouraging to see well known food giants, such as the Jamie Oliver Group, making an effort to reduce the amount of meat they’re offering customers, it’s perhaps not as ambitious a pledge as others have already made.
"It would be great to see the Jamie Oliver Group step it up a little.”
Others in the spotlight who are promoting the vegan cause include baker Freya Cox, just voted off this year's Great British Bake Off on Channel 4.
The 19-year-old cook promised to showcase vegan baking, and created impressive challenges and showstoppers using aquafaba instead of egg white and replacing butter with a vegan alternative.
Judges Paul Hollywood and Prue Leith were complimentary, but Freya went home last week.
Other advocates of the vegan lifestyle include actor Joaquin Phoenix, who used his Joker Oscar winning speech to promote the cause, asking the audience: "Why (do) we feel entitled to artificially inseminate a cow and steal her baby, even though her cries of anguish are unmistakable?”
Pop star Billie Eilish is also a vegan, recently posting: "Leave animals alone. Damn," while Harry Potter actor Evanna Lynch is a campaigner for animal rights and says she stopped eating meat aged 11, after feeling "viscerally repelled by the idea of eating animal flesh”.
Actor Elliot Page is also a vegan who often speaks up on behalf of animals in interviews and on social media.
TV presenter Fearne Cotton has released a vegan cookbook, as has Made In Chelsea star Lucy Watson.
Even veteran star Stevie Wonder is a convert. He turned vegan in 2016, saying: “(It's) helped my already good-looking self. I think that eating healthy is important.”
Others have put their money where their mouths are, with Formula 1 champion Lewis Hamilton recently opening the restaurant Neat Burger, serving plant-based burgers.
Actor Rooney Mara co-founded vegan fashion label Hiraeth and narrated Dominion, a documentary on animal welfare, with her partner Joaquin Phoenix.
Well-known vegan and animals rights advocate Pamela Anderson often appears in campaigns, and recently opened a pop-up vegan restaurant in France.
Lawson may not be ready to climb onto the vegan bus just yet – but plenty of others are already on board.
