When he plans dinners, he has to keep in mind the tastes of his wife (a trained pastry chef), 6-year-old son and 2-year-old daughter. Because of his Hispanic and Asian heritage and his wife’s Italian-Swiss ethnicity, Planells says their menus resemble the United Nations. One dinner might be Korean barbecue with rice, kimchee and spicy cucumber salad. Another might be ribolita (Italian bread soup) with cannellini beans, tomato, onions, kale and bacon. There are two principles that guide Planells’ meal plans: serving high-quality protein and at least two different kinds of vegetables, and a responsibility to expose their kids to new dishes from around the world.
