Prepare the Veggies and Fruits: Shred the cabbage, peel and grate the carrots, slice the cucumber, and chop or slice the apple. Combine all the veggies and fruits in a large bowl.
Make the Dressing: In a small bowl, whisk together the yogurt, mustard, honey, lemon juice, olive oil, and a pinch of salt. Stir until smooth and well combined.
Toss and Serve: Pour the dressing over the shredded cabbage mixture and toss until everything is evenly coated.
Chill and Enjoy: Let the salad sit in the fridge for a few minutes before serving for an even fresher taste.
