Preheat the oven to 200°C (400°F).
In a bowl, toss the diced aubergine with olive oil, cumin, and a little salt and pepper.
Spread the aubergine on a baking tray and roast for 20 minutes or until soft.
In a food processor, combine roasted aubergine, chickpeas, garlic, lemon juice, and additional salt and pepper.
Pulse the mixture until combined but still slightly chunky.
Shape mixture into small bite-sized balls.
Serve warm or at room temperature as an appetizer or snack.
