For extra flavor, consider adding a splash of vinegar (red or white) to the tomato mixture during the last 10 minutes of simmering. Feel free to experiment with different herbs and spices in the flour mixture for the zucchini fries. Smoked paprika or garlic powder would be delicious additions. If you prefer softer fries, skip the second frying and simply keep them warm in the oven after the initial fry. For a richer flavor, use homemade vegetable stock or broth in place of some of the water when simmering the tomato mixture.
