If ever there was a case to prove meat and vegans don’t mix, it is this one.

Award-winning vegan chef Chloe Coscarelli, who formed an unlikely partnership with the owner of the BLT steakhouse chain and his daughter, is now suing them for allegedly making threats in an effort to steal her company.

Coscarelli inked a deal with BLT head James Haber and daughter Samantha Wasser in 2014 to open a vegan version of Shake Shack called By Chloe, according to her Manhattan civil suit.

But when Coscarelli, 28, refused to let Haber open nonvegan eateries in her name, Haber warned “that she would need a bodyguard if she dared to meet with him in person,” the suit says.

Then Wasser signed an agreement that would sell all of her company’s assets to Haber in exchange for a $5 million loan, the suit says.

Coscarelli claims she never approved the deal.

An attorney for Haber and Wasser said their company “has always — and will continue to — act in the best interest of By Chloe.”
