Vegetable soup with meatballs

We're making the most of the end of winter here. Our first day of spring is 1 September, already the days are warming up but the nights are still cold. Soon they'll even out and we'll be looking for cool drinks and throwing open the windows. Tonight I wanted to make a nourishing soup, that didn't cost too much, and would serve us well for a few nights. We're going out to Bell again on Saturday
