People for the Ethical Treatment of Animals has ranked Gillette Stadium No. 2 on its annual list of vegetarian-friendly stadiums. On its website, PETA highlights the “mouthwatering vegetarian options” at the stadium’s 38 permanent concession stands, singling out such items such as black-bean burgers, grilled portobello mushroom burgers, and grilled veggie flatbread wraps. “We wanted the new menus to reflect the changing taste of our guests,” said James Nolan, Gillette Stadium’s senior vice president of operations, administration, and finance. “Our research suggested that our fans were seeking more vegetarian options. They have been some of our best sellers.” Gillette Stadium was No. 4 on the list last year.
