San Antonio-based Mark Menjivar thinks of his project, “You Are What You Eat,” as a series of intimate portraits. “One person mentioned that ‘asking to photograph my refrigerator is like asking me to pose nude,’” he says. Menjivar, 29, a professional photographer with a degree in social work, came up with the idea while working on a documentary film about hunger. “I was thinking about how ‘you are what you eat’ is a cultural cliché, but is also very relevant.”
