Potatoes are best washed the day before and cooked in boiling water for about 20 minutes until firm to the bite. Drain potatoes, quench, peel and let them cool down
Wash the meat and rosemary and dab dry. Place rosemary twigs in the middle of the fillets and tie them with kitchen string. Clean and wash the zucchini and peppers. Cut the zucchini into slices and the bell peppers into strips. Wash thyme, dab dry. Remove the leaves from the stems and chop finely
Heat 1 teaspoon of oil in a frying pan and fry the steaks on both sides for about 1 minute, season with salt and pepper and continue to fry over medium heat for about 4 minutes, turning them over (also fry the sides all around). Wrap the finished steaks in aluminium foil and let them rest for about 5 minutes
In the meantime, heat 1 tablespoon of oil in a large coated pan. Fry the potatoes in it at medium heat for about 6 minutes until golden brown. After approx. 2 minutes add paprika and zucchini and fry as well. Season with salt, pepper and thyme. Finally crumble feta cheese and pour over the vegetables. Arrange fillet steaks with potatoes and vegetables on plates
