In a food processor, combine the chickpeas, tahini, olive oil, lemon juice, garlic, cumin, and salt. Blend until smooth.
Gradually add water, one tablespoon at a time, until the hummus reaches your desired consistency.
Transfer the hummus to a serving dish and create a shallow well in the center.
Arrange the cherry tomatoes, cucumber, red onion, olives, and feta cheese in the well and around the hummus.
Drizzle a little olive oil over the top and sprinkle with chopped parsley.
Serve with pita chips or fresh veggies for dipping.
