One way of encouraging your fussy eater to taste new foods is to play with the colours. If you get a chance to go to the supermarket with them you could ask them what colour they would like their dinner to be that evening. If they say red, then you could give them fish covered in tomato sauce (http://kinderkitchenrecipes.blogspot.co.uk/2009/03/todays-nutritious-recipe-from-kinder.html) or pasta with tomato and red pepper sauce. If they say blue you could make them a fruit wand (recipe below). You could try cooking an aubergine and ask them to try it and tell you what ‘purple’ tastes like. Pizza faces can be very colourful using peppers, sweetcorn, peas(http://kinderkitchenrecipes.blogspot.co.uk/2013/06/healthy-kids-recipes-homemade-popcorn.html). The key is to try and be inventive.
I found these on a wonderful website called Weelicious. For the recipe go to http://weelicious.com/2012/06/29/magical-fruits-wands-for-your-fourth-of-july-celebration/
