Place the cabbage in a large bowl and sprinkle with the kosher salt. Massage salt evenly into the cabbage with your hands until it starts to soften. Let sit for 5-10 minutes.

To the cabbage, add the grated carrot, scallions and dill. Mix to combine.

Dress with sunflower oil, vinegar, and pepper and mix until evenly combined. Taste for salt and acidity and adjust if necessary.

Refrigerate for 15-30 minutes before serving to let all the flavors come together and for the cabbage to soften a bit more. Garnish with fresh dill right before serving.
