These fritters could be served as appetizers, as a side dish or as one of several vegetarian dishes. It's the closest recipe I've found for some delicious zucchini fritters I ate and loved some years ago, though I'm pretty sure that they didn't have sumac in them, and sumac adds a lot of flavour. When I inquired after the recipe at the time, the Greek woman who'd made them she named the key ingredients but was very dismissive of them. I felt as if to her it was if I'd asked how to make something as simple as say a basic bread and butter sandwich with a slice of cheese in it! This recipe is from the Australian Women's Weekly's 'fresh food fast: delicious no fuss healthy recipes'. Australian brown onions are what Americans call yellow onions. Sumac, if you've not used it is defined (in the same recipe book) as "a purple-red astringent spice ground from berries that grow on shrubs that flourish wild around the Mediterranean; has a tart, lemony flavour. Found in Middle-Eastern food stores. Substitute: 1/8 teaspoon five-spice plus 1/2 teaspoon lemon pepper plus 1/8 teaspoon all spice equals 3/4 teaspoon sumac". I've found that I can purchase it readily from more upmarket supermarkets and European delicatessens.
