I like zucchini very much. I also like simply frying them with a pan.
Just spread some oil in the pan. Put zucchini slices in the pan. When the downside turn a little golden brown, flip them over and fry the other side. Spread some salt and black pepper. When both side are done, take them out in the plate.
You can stir fry zucchini with sausage slices, which also tastes good.
