Clean and wash the cabbage and slice or cut it into fine strips from the stalk. Knead vigorously with about 1 teaspoon salt. Peel and finely chop the onion.
Heat 2 tablespoons of oil. Fry the onion until transparent. Deglaze with vinegar, bring to the boil. Remove from heat, stir in mustard and honey. Season with salt and pepper. Pour marinade hot over the cabbage, mix everything and add at least a little bit of the marinade.
Leave to steep for an hour.
Defrost the prawns if necessary. Peel and wash the carrots and cut them into thin sticks or grate them roughly. Peel and quarter pineapple and cut out the stalk. Cut the fruit flesh into bite-sized pieces.
Wash parsley, shake dry and chop coarsely. Mix everything into the cabbage.
Wash the prawns, dab dry. Fry in 1-2 tablespoons of hot oil on each side for about 2 minutes. Season with salt and pepper. Season salad again and arrange with the prawns.
