Combine mustard, yoghurt and vinegar in a small bowl. Place the cabbage, capsicum, spring onion, caraway seeds and dill in a large bowl, then add the dressing and toss to combine.
Place the spice and oil in a bowl and stir well to combine. Add cutlets and rub all over with the mixture. Lightly oil a large frypan and place over medium heat. When hot, add cutlets in batches, and cook for 3 minutes, turning once for medium-rare, or until cooked to your liking. Serve with coleslaw.
