In a food processor, add broccoli, boiled potatoes, oregano, black pepper, salt, and cream cheese.
Pulse the mixture until well combined. The consistency should be thick enough to shape into balls. If it feels too soft, refrigerate for 15 minutes.
Lightly oil your palms to prevent sticking. Take a small portion of the mixture and roll it into a smooth ball (about 1-inch in size). Repeat with the remaining mixture to form all the balls.
In a shallow plate, mix bread crumbs and sesame seeds.Roll each veggie ball in the mixture, ensuring an even coating. This will give a crunchy texture when cooked.
Preheat the air fryer to 180°C (350°F) for 2-3 minutes.Place the veggie balls inside the air fryer basket in a single layer. Do not overcrowd.Lightly spray or brush oil over the balls.Air fry for 12 minutes, shaking the basket halfway through for even cooking.Once golden brown and crispy, remove and serve hot.
For deep frying, heat oil in a deep frying pan over medium heat.Drop a small piece of the mixture into the oil—if it sizzles and rises, the oil is ready.Carefully place the veggie balls into the hot oil in batches.Fry for 3-4 minutes, turning occasionally, until golden brown and crispy.Remove and place on a paper towel to drain excess oil.
