Preparation

Preheat the oven to 350\u00b0. Cook the beans in boiling salted water for 4-5 mins. Drain and rinse under cold water. Heat the oil in a large frying pan and cook the steaks for about 3 mins, until brown on both sides. Remove from the pan and bake for about 10 mins.
Meanwhile, to make the sauce, add 1 tbsp of the butter to the frying pan, add the mushrooms and 1 stem of rosemary and cook for about 3 mins. Deglaze the pan with vinegar and stock and simmer for 2-3 mins. Mix the cornstarch with 2 tbsp water and add to the sauce, stirring until thickened and smooth.
Melt the remaining butter in a pan and saute the onions until transparent. Add the green beans and sprinkle with the remaining rosemary leaves. Cook for 3-4 mins. Season with salt, pepper and sugar. Arrange the steaks and green beans on serving plates and top with sauce. Serve with ciabatta bread.
