1. Soak a stale roll in water, squeeze it out well, and add it to a bowl together with the ground meat, onion, egg, breadcrumbs, mustard, salt, and pepper, then mix everything thoroughly.
2. Form equal-sized balls from the mixture and press them slightly flat to ensure even cooking.
3. Preheat the Airfryer to 180 °C. Place the balls in a single layer in the basket and cook for about 15–18 minutes. Turn them halfway through the time until they are golden brown on the outside and cooked through inside.
