In a medium bowl, mash drained and rinsed chickpeas with a fork. Add the remaining ingredients and stir to combine.
Prepare desired toppings, such as sliced red onion, tomato or avocado.
If serving as a sandwich, toast bread and serve between slices with toppings. If serving with romaine lettuce leaves, top leaves with chickpea mixture and toppings. Alternatively, serve as a dip with sliced vegetables.
To round out the meal, pair with baby carrots or a piece of fruit.
