The organization also pointed out that 42 of America's 'favorite' food chains were missing a 'huge' market opportunity by not offering any vegan entrées.
McDonald's, KFC, Wendy's, and In-N-Out-Burger were amongst the major eateries to receive zero points (out of 10). While Del Taco (10), Jamba Juice (10), and Panera Bread (9.25) earned a place in the top five.
'A business imperative'
In a statement sent to Plant Based News, The Good Food Institute Foodservice and Supply Chain Manager Zak Weston said: "More top U.S. restaurants are stepping into plant-based or stepping up their existing game to cater to customers looking for more center-of-plate protein variety.
"Having a strategy for plant-based is now a business imperative - your customers want it and your competitors are doing it."
'The tipping point'
While Sara Burnett Vice President at Panera Bread - who recently announced it is committed to turning 50 percent of its menu plant-based, added: "We're at the tipping point where consumers are demanding plant-based foods and the industry is willingly responding with delicious options.
"This is no longer about a niche customer- it's a major business opportunity."
