I am a big fan of faces because they are just so easy and lets face it (pun intended) your kid will always recognize a face. I have made things for them that I had to explain and that is never good.
I cut some grapes in half for the hair and used half a piece of bacon for the mouth. The nose is a wedge of string cheese and the eyes are wheat bread with nutella. I cut the eyes out using a medium sized circle cookie cutter and added marshmallows for the eyeballs. Using my trusty Wilton food writers, I made the pupils. You can add some banana ears if you'd like, but I was fresh out of bananas. There a million variations and things you can play with. Make it your own.
Super easy and impressive, especially if you're a kid. Think you have to spend a long time to make a fun meal your kids will remember? This took all of 5 minutes. And they ate it all which is a rarity in this house. For more food ideas check out Food Fun.
