Cut the onion and zucchini into medium pieces and season with salt and pepper. In a pot, add olive oil and sauté the vegetables for about 5 minutes.

Peel the melon, remove the seeds and rind, cut into pieces, and add to the pot. Stir and turn off the heat.

Transfer the mixture to a blender and blend until smooth.

To finish, fry the diced ham and some bread cubes for croutons to serve on top. I also added chia seeds and white and black sesame seeds.
