Heat the airfryer to 180°C (350°F). Or use a regular oven.
Place breadcrumbs/panko in a big bowl with the water, set aside
Peel and finely chop the onion, add to the bowl
Add ground chicken, egg and all the spices to the bowl and mix together
Form into balls of around 5 cm (2 inches)
We used an airfryer for 10 min but I guess it would work just fine to fry it in a normal pan or in the oven
