Place the romaine lettuce on a plate. Top the lettuce with black beans, tomato, avocado, mango, red onion, and cilantro. Squeeze fresh lime juice over the lettuce and toppings. Enjoy! It is that easy! If you want to warm up the black beans, you can. I like them hot or cold. If the lime juice isn't enough dressing for you, you can add
salsa for a healthy dressing.
