Eat your veggies.

How do I get this kid to eat fruits and vegetables?  When I first started him on solid foods he absolutely LOVED everything I put in front of him - spinach, bananas, apple sauce, carrots - you name it he ate it.  Not any more. 

Once he discovered meat, bread, and cheese he made up his mind these were his three true loves.  This new awareness that he has opinions has met with his propensity for slapstick and blown into a sort of culinary perfect storm.  He puts food he refuses to eat on his head, then calls it a hat.  Kernels, nuggets, berries, or peas he will squish with a finger or send flying with a swoosh of his chubby hand.  He enjoys fruits and vegetables, he just doesn't eat them.

I've read the how-to-hide-healthy-food-in-their-food-books, but what I'm looking for now are tips or secret potions.  Whatcha got?
