These tasty Tofu Zucchini Patties have been adapted from a recipe I found in The Australian Women's Weekly's 'The Health Cookbook'. When I've made them for friends, as a casual luncheon dish, they've always been popular - including with those more conservative diners who had never previously eaten tofu! I've suggested serving them specifically with Greek yoghurt - as that's what I generally use - but I've also served them with tzatziki. If you're looking for a recipe for tzatziki, it's hard to beat Ravenseyes' Recipe #306901 or Recipe #157176. BTW, Australian brown onions are what Americans call yellow onions. The original recipe specified "1 cup packaged breadcrumbs" which I've left in the posted recipe but when I've made these I have used processed fresh breadcrumbs. If you find it easier, you can also process the onion and garlic. I've made the herbs optional as you may prefer some other herb combinations, and if you like your food spicier, feel free to modify the recipe so that it best meets your taste preferences.
