Soak 1 roll (from the previous day) in a bowl of cold water and squeeze it well. Peel 1 onion, dice finely. Wash 4 stems of parsley, shake dry, pluck the leaves and chop finely.
Put 500 g mixed minced meat, 1 egg (size M), 2 teaspoons medium hot mustard, onion, bread roll and parsley in a bowl. Strongly season with salt, pepper and 1-2 teaspoons sweet paprika powder and knead with your hands.
Form 8 meatballs with moistened hands. Wrap 1 slice of bacon around each. Press the ends of the bacon lightly. Heat 3 tablespoons of oil in a large pan. Fry the meatballs on each side for about 6-8 minutes until crispy.
