Jose and Leticia Gamiz received many insults when they first opened their Mexican food business four years ago. Their business, called Mi Vegana Madre, is entirely vegan. In other words, they only serve food made from plants. “That’s not real Mexican food,” some people said. My grandma would slap you” was another comment. “We even had somebody write online in Spanish, ‘They’re probably not even Mexican,’” Jose Gamiz told the Associated Press. But even so, the couple’s meat- and dairy-free business has built a following. And, it is part of a growing vegan Mexican food industry in the United States.
