Gather the ingredients.
In a large bowl, combine the drained and rinsed black beans , the diced bell pepper, green onions, minced jalapeno pepper, and fresh cilantro.
In a separate small bowl, whisk together the olive oil and lime juice (and the hot sauce if you're using hot sauce instead of fresh jalapeno pepper).
Pour the olive oil and lime juice mixture over the bean mix, and gently toss together until well mixed.
Once the ingredients are well combined, carefully and gently fold in the diced mango and season lightly with sea salt or kosher salt.
You may want to taste, and adjust the seasonings, or add a bit more salt before serving.
