How Do I Get My Kids To Eat More Fruit And Vegetables?

Buying them something: when you're out and about and they moan they're hungry (or even before they're hungry), go to the green grocer's and let them choose something to snack on.
Nothing else on offer: don't have snacky foods in the house like crisps, chocolate, biscuits; or have a rule that these things are limited.  But do keep a big bowl of fresh fruit in reach, ideally somewhere near the TV screen.  Put out a plate of something like cut up carrots, celery and cucumber out and low-fat sour cream dip when they are slouched in front of the tv waiting for you to cook tea.
Playground hostages:  Use their natural inclinations to your advantage.  When you take them to the playground (or beach, or woods) take a stash of fruit they might eat and don't take anything else (except water).  Eventually, hunger will compel them to snarf up what's on offer rather than have to leave the playground to get something else.
Wild harvests: take them for walks in late summer and autumn where blackberries grow.  Hunger and curiousity will get the better of them, and they'll start nibbling on the hedge.
Crumbles:  Crumbles are easy and cheap to make, most kids like them, and they can be very healthy (add minimal sugar to still make it taste nice, and serve with yogurt or cream rather than ice cream if possible).  You can involve the kids in cooking, too.  Take some bags or plastic posts with you on that late summer walk and collect blackberries for crumble then.  Many people have plum and apple trees that burst with too much fruit in late summer; cultivate these people as friends.
Vegetable water: when you cook vegetables, the water is full of vitamins, so save it for cooking the next day, or making bread.  Using this water to cook with rice or pasta means that the rice/pasta will soak up some of the vitamins.  Some young children will drink veg water on its own, or with a little fruit juice.  
Don't let them fill up on other stuff: they won't be hungry for a banana if they've just sucked down a bottle of fizzy.  Try to keep drinks to mostly water and offer fruit before anything high in calories.

Make the meals more interesting! Substitute fruit for sweets on occasion too, just for a change. Make an offer of once the fruit and vegetables are finished, there's a good dessert - one with fruit in it, for example!

There are these things that give you a days worth of fruits and vegetables in a pill but for kids they make them in gummy form.  Or make the meals interesting
