Wash the peaches and watermelon thoroughly, then slice the peaches into bite-sized pieces, discarding any pits.

Cut the watermelon in half, scoop out the flesh, and chop it into similar-sized cubes.

Crumble the feta cheese and finely chop the fresh mint. Place all prepared ingredients in a large mixing bowl.

In a small bowl, whisk together balsamic vinegar with honey until well combined.

Taste the dressing to adjust the sweetness and set it aside.

Gently combine the chopped peaches, watermelon, and fresh mint in the large bowl.

Before serving, drizzle the prepared balsamic dressing over the salad mixture and toss gently.

Transfer to a serving dish or bowl and serve immediately.
