For the Turkey Filling:

1. 1. In a large skillet over medium heat, add 1 tbsp olive oil.
2. 2. Add ground turkey and cook until browned (about 5-7 minutes), breaking it apart as it cooks.
3. 3. Once browned, sprinkle in taco seasoning. Stir well and pour in water or broth. Let simmer for about 5 minutes until thickened.

For the Bowl:

1. 4. Rinse black beans under cool water. You can warm them in a small saucepan over low heat or add them directly to the turkey mixture during step three.
2. 5. In individual bowls, layer shredded lettuce as the base, followed by the seasoned turkey with black beans on top.
3. 6. Finish with cherry tomatoes, diced avocado, and a generous dollop of sour cream or Greek yogurt. Customize with any extra toppings like cheese or cilantro if desired.
