As plant-rich diets become all the rage, one ex-Wall Streeter and animal-rights activist is banking on vegan burgers.

VBurger, a fast casual meatless burger joint, is opening later this month in Union Square, at 815 Broadway, where it will share space with The Hummus & Pita Co.

Robert Cox, a former banker and an animal rights advocate, is a co-founder along with Reese Martin.

Burger options will include the Einstein, made from cauliflower and potato. In addition, 10 percent of VBurger profits will go to Mercy for Animals.

The eatery will also cater to those with allergies or food sensitivities. The menu is nut-free except for almond milk used in milk shakes. There are also gluten-free options.
