Cuban Black Bean Soup, also known as 'Sopa de Frijoles Negros,' is a hearty and flavorful soup made with black beans, onions, garlic, peppers, and spices. The beans are cooked until tender and then blended to create a thick and creamy soup. The soup is often served with a dollop of sour cream and a sprinkle of chopped cilantro. It is a popular dish in Cuba and is enjoyed as a comforting and satisfying meal, especially on cooler days.
