Cut watermelon in half and remove watermelon from rind (use half of the watermelon as your bowl). Cut watermelon flesh it into squares, or scoop it all out with a melon baller.
Make dressing (olive oil, balsamic and pepper).
Pour dressing over watermelon and chill for 15 minutes while you cut the mint.
Roll up the mint leave like a cigar and then cut it into strips or ribbons.
