Many fruits and vegetables that we could never dream of buying even as a treat are now readily available at supermarkets. Have you discovered fennel, lacinato kale, chayote, pomegranates, loquats, passion fruit, or ripe plaintains?
Is there a greenmarket near you? Discover the joys of seasonal produce and watch the the seasons go by in rhythm with the market: ramps, spring garlic, cherries, berries, apricots, tomatoes, apples, eggplant, peppers, tatsoi, kale, turnips, corn. Take your children with you and discover these things together. Or take a trip to your local Chinatown and discover green things and fruits you never knew existed.
Instead of white rice or spaghetti, try farro, quinoa, kamut, and wild rice. They are delicious, easy to cook, and highly nutritious.
Remember: we are what we eat. Do you want your children to be eating bad food?
