In a saucepan on the side burner or stove top over low heat, melt the butter. Add the onion and fry for a few minutes until golden and just beginning to soften. Remove the saucepan from the heat, and set aside to cool.
Prepare the barbecue for indirect cooking over medium heat (180°C to 230°C). If using a Weber Q barbecue, set up your barbecue with a convection tray and a trivet.
Once the onion is cooled, mix with the remaining ingredients. Using heaped tablespoons worth of mixture, roll into balls.
Put the stuffing balls into a drip pan that has been lightly greased with butter. Roast the stuffing balls over indirect medium heat, with the lid closed, for 10 to 15 minutes, or until cooked through.
