# Prepare the liaison at first; grate the
onion, add
olive oil, salt and black
pepper in it, and mix. Dip the beefsteaks into this mixture, cover and refrigerate them overnight.
# Grill or cook the rested beefsteaks in the skillet with some butter.
# In the meantime place the grated kashar
cheese into a heat resistant cup, and place this cup into the pot which is full of water, and place this pot over medium heat. By this way melt the kashar and make it liquid.
# Pour the melted kashar
cheese all over the beefsteaks just before serving. # You can garnish with
potato puree also while serving.
