Every holiday season, things get a "bit tricky," says Risa Greene, 53, from New York City. "You have one child who is a human garbage disposal and will eat anything you put in front of him, and you have another child who is more restricted than [the] TSA."
Greene's son is an omnivore — he eats everything. Her daughter, Jessica, is a vegan. She stopped eating meat when she was in high school years ago, then dropped dairy products and eggs in college and eventually gave up gluten, too.
