In a large skillet, cook ground beef until browned and cooked through. Stir in taco seasoning and 1 cup water. Bring to a boil, then reduce heat to medium-low. Simmer until most of the liquid evaporates.
In a large bowl, use two thirds of the lettuce to create the base layer. Follow with sliced black olives and two thirds of the halved tomatoes. Top with remaining lettuce.
Next, layer peppers, black beans and shredded cheese. Top with warm taco meat. Garnish with sour cream, avocado and remaining tomatoes. Toss to serve.
Note: Serve with your favorite salad dressing, if desired. Nutrition information does not include added dressing.
