My adaptation of a recipe from the Summer 2009 Coles magazine, where it's listed as costing $A1.75 per serve. I've added several herbs, an apple and walnuts to the original recipe. Apple in meatballs adds moistness and flavour. If you want to keep the price down, perhaps add some extra onion, some more apple (depending on the price of apples) and then some more breadcrumbs - and either omit or reduce the quantity of walnuts. Another way of stretching this recipe further would be to add a can of drained, processed butter beans in step one, before shaping the mixture into meatballs. I've added herbs I particularly like: please feel free to vary the herbs to meet your taste preferences and to vary the quantities. I've specified mincing the onion, garlic and apple as I process mine in a mini processor. All of these could, of course, also be finely chopped. And if you're not overly fond of lemon, do consider an alternative!
