So, it makes sense that a vegan fast food chain is jumping on the healthy trend. Veggie Grill launched ten years ago, and it now has 28 locations on the west coast. But after a $22 million bump from investors, the chain is preparing for a nationwide expansion and plans to double in size in the next four years.
