To prepare the creamy garlic dressing, add the soaked cashews, water, salt, pepper, garlic and onion powder, and apple cider vinegar to a blender. Blend on high until fully smooth. Add additional water if needed to reach your desired consistency. Place in the fridge to chill.
To prepare the crispy chickpeas, heat the olive oil in a large skillet over medium heat. Add the chickpeas, salt, pepper, and garlic powder. Stir to combine. Cook over medium heat until crispy and golden brown, about 10 minutes.
To assemble the salad, layer romaine lettuce, cucumber, garlic pickles, cabbage, and hummus. Add any optional additions such as pickled turnips or red onions, sauerkraut, or tabouli. Top with the crispy chickpeas and drizzle with the creamy garlic dressing. Enjoy immediately.
For leftovers, store all toppings separately. Reheat the chickpeas in a skillet until crispy and assemble the salad.
