Slice the top off 2 Oranges in a zig zag motion and use a knife to cut round the flesh inside, to loosen it.
Scoop out the flesh and set aside.
Carefully, use a knife and carve your face out.
Fill the fruit cups with 150 g Blueberries and 150 g Grapes.
Replace the top and serve.
Notes
You could swap the oranges for grapefruit
If you didn't want to cut the faces out of the orange, then you could just use a permanent marker to draw them on. This is a way to get kids more involved. Or, they could draw the faces they want, and then a grown-up can cut them out.
