Make the vinaigrette: In a small bowl or jar, whisk together all vinaigrette ingredients until well emulsified. Taste and adjust salt, sweetness, or acidity if needed.
Assemble the salad: In a large bowl, combine chickpeas, cranberries, walnuts, parsley/spinach, and cucumber (if using).
Dress and toss: Pour the vinaigrette over the salad and toss gently until everything is evenly coated.
Chill or serve: Serve immediately or refrigerate for 15–20 minutes to allow the flavors to blend beautifully.
