Bring a small pot of water to a boil over high heat. When the water is boiling, add the green beans and blanch for 2 minutes. Drain and rinse under cold running water.
In a small mason jar, add the red wine vinegar, olive oil, nutritional yeast, cane sugar, salt, oregano and pepper. Place the lid on tightly and shake.
In a large bowl, toss together the romaine, kohlrabi, green beans, cucumber, chickpeas, olives, green onions and sunflower seeds. Drizzle the dressing over the salad and toss again.
