So you want something healthy eh. Hmmmm .....
it depends on what the other kids like. Personally i know a few things that i do that soem younger children i know really enjoy.
First of all, The one for kids that love cheese, mix 2 parts boursin cheese and 1 part cream cheeselet it firm up slightly i the refrigerator. Next get some seedless red grapes (red flames would probably work well) and wash them throughly. This is where it will get messy and you will have to work really fast (at my top speed i can do about 75 grapes in about 30-45 minutes ... that is my best mind you). Next step is to encase the grapes in the cheese mixture. take a small amount of the cheese and flatten it slightly in your palm (it helps if you work with small batches of the cheese so it doesn't melt that fast and it helps if you naturally have cold hands like my fiancĂ©e). next take the grap and place it in the center of the cheese and then roll it around in your hands. Don't work it too much and just so you know, cheese WILL get onto your hands. Once the grape is covered as evenly as possible place it on a tray and refrigerate once the tray is full. Let the cheese firm up again. if you want, you can stop here OR you can then roll the grapes in something else like a herb mixture (mostly parsley) or something sweeter or crunchier.
The other idea would be why not fresh fruit tarts? You can buy these very tiny tart shells in a lot of grocery stores. Bake off the tart shells and then fill them up with some fresh fruit that is high in natural sugars (oranges, blood oranges, strawberries or preferably blueberries) ... be sure to chop them up quite fine if the fruit is larger in size. Then top them off with a drizzle of white chocolate (not really chocolate ... but oh well) or a dark chocolate that is high in cocoa butter. The high cocoa butter chocolate will cost a lot more but TRUST ME it will most definately be worth it. Not only does it taste better but it is actually healthier for you (yes .. chocolate isn't all bad for you if it is the GOOD chocolate).
you could also try making some small fresh fruit crepes. They are always a party favorite ... but thin crepes are a pain to make properly for even those who are more experienced then i am.
So there are a few ideas. hope that helps with the healthy part of your original post.
