Soups are a great way to introduce a lot of vegetables to kids. Stir-fries, too, because they contain so many different shapes and colors.
I love fresh citrus and always keep lemons, limes, and oranges on hand; they come in handy for spritzing up quickly grilled meats, seafoods, and vegetables, especially when followed up by a quick drizzle of extra virgin olive oil.
A lot of parents ask me how to get kids to eat more vegetables. The first thing I say is that it starts from the top.
