1. Heat a non-stick skillet over medium heat. Add the ground turkey and cook until browned and cooked through, about 6–8 minutes.
2. Add the chili powder, cumin, granulated garlic, onion, oregano, salt, and ¼ cup of water. Stir well, reduce the heat to low, and let the turkey simmer for 10 minutes so the flavors blend.
3. While the turkey simmers, prepare the dressing by adding the soaked cashews, avocado, garlic, salt, lime juice, cilantro, and ½ cup water to a blender. Blend until smooth, adding more water as needed to reach a creamy dressing consistency.
4. Assemble the salad by adding romaine, black beans, tomatoes, corn, and turkey to a large salad bowl.
5. Drizzle with the creamy avocado dressing and toss gently to combine. Divide into bowls and garnish with chopped cilantro and avocado slices if desired.
