Make the tzatziki dressing: In a large bowl, whisk together Greek yogurt, grated garlic clove, olive oil, honey, and the juice of half a lemon (or more to taste). If it seems too thick, loosen with a splash of aquafaba or a little more lemon juice. Season with a pinch salt and pepper, to taste.
Toss the salad: Add cucumbers, olives, chickpeas, dill, mint, and scallions to the bowl and toss everything to coat. Adjust taste with added salt, pepper, lemon juice or olive oil as desired.
Serve: Transfer to a serving bowl or plate and finish with extra sprigs of dill and/or drizzle of additional olive oil.
