Core, peel and cut the melons into large cubes. Skewer the cubes alternately. It is also nice to use different colored honeydew melons with the watermelon.
Finely chop the oregano and orange zest. Mix everything with the spices and sprinkle the melon skewers with them.
The skewers can be served as a starter or as a decoration for a watermelon gazpacho. (Recipe in my profile).
