In a medium pot, add barley and water and bring to a boil. Once boiling, reduce heat to low, cover and cook for 20 min. Barley should have absorbed all the water and should have a soft chewy texture. Remove from heat and set aside.
Salad Dressing
In a small bowl, whisk yogurt, Dijon mustard, garlic, lemon, vinegar, thyme and olive oil.
Salad
In a large bowl, combine kale, cabbage, onion, parsley and warm barley.
Pour salad dressing over and mix well. Season with salt and pepper to taste.
Top with sunflower seeds and parmesan cheese. Enjoy!
