Whatever you do don't give into his picky eating habits! Give him an option eat what he is given or don't eat. I promise he will not starve because he misses a meal or two. I know this sounds harsh but the more you give into him now the harder it will be to break the habit later. Try cutting up the food in to pices that he can handle on his own.
That said my sons (12 and 7) came close to living on chicken nuggets and french fries at one point in there lives. Eventually they got tired of them and were willing to be more adventerous with food.
