Prep your ingredients: Rinse and drain chickpeas. Chop all vegetables and herbs.
Make the dressing: In a small bowl or jar, whisk together olive oil, lemon juice, Dijon mustard, garlic, salt, and pepper.
Toss the salad: In a large mixing bowl, combine chickpeas, tomatoes, cucumber, red onion, bell pepper, and parsley.
Add dressing and mix: Pour dressing over the salad. Toss until everything is evenly coated.
Top with feta (if using): Sprinkle on top before serving or stir gently to combine.
Serve immediately or chill for 30 minutes to let the flavors meld. It’s bright, crunchy, and so satisfying.
