Place drained and rinsed chickpeas in a large bowl and gently mash them until they're about halfway mashed.
Zest lemon over the chickpeas then slice in half and juice the lemon into the bowl. Add all remaining ingredients to the bowl and toss well. Check for seasoning and adjust accordingly. Serve room temperature or chill to enjoy later.
Store in an air-tight refrigerated container for up to 4 days.
