Wash the dill, shake dry and chop the flags finely, except for 1 stalk. Mix sour cream, vinegar, chopped dill and milk and season to taste with salt, pepper and a little sugar. Wash, clean and halve the cucumbers.
Cut or slice the cucumber halves lengthwise into thin slices. Mix cucumber slices and sour cream. Heat oil in a pan. Fry the cheese steaks in it from both sides for about 4 minutes until golden brown (alternatively you can also prepare the cheese on the grill).
Season the ketchup with some chilli powder. Remove cheese steaks from the pan and serve with salad and ketchup. Garnish with pink pepper berries and dill.
