Scoop any seeds from the centre of the melons with a spoon and discard.

Using a melon baller, cut spheres from each melon and pop into bowls until ready to use.

Thread three melon balls onto each skewer, one of each colour, arranged in traffic light order.

Repeat until you have used up all of the melon balls, then pack the traffic light kebabs into a lunch box ready for your picnic.
