Wash the zucchini and cut into approx. 1 cm thick slices or sticks. Season if necessary and toss in the polenta. Melt the butter in a pan and fry the zucchini until golden. Drain on paper towels and serve.
If the zucchini sticks are fried too long, there is a risk that they will become quite soft. Most people prefer the schnitzel a little more firm to the bite.
I advise against replacing the corn grits with breadcrumbs, because it is heavier and soaks up more fat. As a result, it also falls off quickly. If necessary, use conventional breading.
