Hamburgers with Ground Meat

Place the ground meat, quark and breadcrumbs in a bowl and mix thoroughly.

Season generously with salt, pepper and paprika powder and form the mixture into 4 round patties.

Halve the hamburger buns, spread mustard on the bottom halves and place a lettuce leaf on each.

Heat a frying pan.

Fry the patties on both sides in the hot pan until cooked through and browned on the outside, then place them on the prepared bottom buns.

Briefly fry the tomato slices in the pan's drippings on both sides and place them on the patties.

Add a dollop of tomato ketchup, top with the bun lids and serve immediately.
