Add all the meatball ingredients together into a bowl and mush together until all the ingredients are combined. Roll into smaller than golf ball sized meatballs and place onto a large plate.
In a large pot fry the vegetables in the butter on a medium heat for 20 minutes. Add the flour and stir so it coats everything. Slowly pour in both the stocks to create the sauce. Stir so there are no lumps. Add the rest of the soup ingredients except the pasta, double and sour cream. Bubble away for 20 minutes.
