Gather fresh ingredients. Cut the honeydew melon in half and scoop out the flesh into balls or cubes. Rinse and drain blackberries, prepare watercress, and slice shallot.

In a large mixing bowl, add honeydew melon, blackberries, watercress, and shallots. Toss gently to combine without bruising the blackberries.

In a small bowl, whisk together olive oil, lemon juice, honey, and sea salt until emulsified.

Drizzle dressing over the salad and toss gently for about 30 seconds. Serve immediately or let it chill for 10-15 minutes.

Before serving, taste and adjust seasoning with more sea salt if needed. Garnish with extra blackberries or watercress.
