For optimal freshness, ensure the kale is thoroughly dried after washing and before massaging. Feel free to customize your salad with other vegetables like cucumbers, bell peppers, or shredded carrots. To make this salad vegan, substitute the Parmesan cheese with nutritional yeast or a vegan Parmesan alternative. If you prefer a sweeter dressing, add a touch of honey or maple syrup to the vinaigrette. Packing the ingredients tightly helps to prevent the kale from wilting and keeps the salad fresh longer.
