Soak the stale bread roll or white bread in 1/4 cup of milk for about 5 minutes until soft. Gently squeeze out excess milk.

Transfer soaked bread to a large mixing bowl. Add ground beef, chopped onion, minced garlic, mustard, paprika, salt, and black pepper. Add egg and chopped parsley, and mix thoroughly.

Shape the mixture into uniform patties about 1.5 cm thick.

Heat 2 tbsp of oil in a pan over medium heat until it shimmers.

Add the shaped patties to the hot oil in a single layer and fry for about 4-5 minutes until golden brown.

Flip each patty and cook for an additional 4-5 minutes until cooked through.

Transfer cooked patties to a plate lined with paper towels to absorb excess oil.

Serve warm with sauerkraut or creamy potato salad.
