Most of the organic food shops (at least in Auckland) will deliver a weekly veggie box to your doorstep! You may indicate your likes and dislikes and they will try to accommodate it. There's no easier way to assure that you eat your 5 servings of vegetables a day (there's always something about to go off in your fridge and it just MAKES you cook and be creative with recipes!) What could be more exciting than ripping a box open to see what's for dinner tonight?!? And someone else does the walking/driving for you!
I tried several shops in West Auckland and decided to stick with the one in Pt Chev. 30$ a week for a (they call it small) box of organic veggies and fruit (apples do taste like apples from my childhood. What on Earth have I been eating all these years?!?!) Talk to your local organic shop. They may have a similar service!
