In a small bowl, whisk together olive oil, minced shallots, white wine vinegar, honey, sumac, and salt to make the dressing. Set aside.
Thinly slice cucumbers, radishes, and celery, then add them to a large mixing bowl.
Add minced dill, chives, and chopped mint for a fresh, aromatic flavor.
Drizzle the prepared dressing over the salad and toss gently to coat.
Crumble goat cheese over the top and lightly mix to combine.
Let the salad sit for 5 minutes to allow the flavors to meld.
Serve immediately, or chill for 10-15 minutes for enhanced flavor.
