Monster Burger

Slice the onion and fry until golden brown in a pan with hot oil.

Knead the minced meat with salt and pepper and form into two uniform balls. Flatten each ball into a round patty. Form a small indentation in the center of both meat patties. Fry both meat patties in a pan with hot oil for approx. 5 to 6 minutes on each side.

Cut overlapping triangles from the cheese slices one after another, so that most of the slice gradually gets ghostly teeth.
