Add the chicken broth and increase the heat to high; bring to a boil and cook 1 minute. Reduce the heat to medium low, cover and simmer until the spaghetti is almost fully cooked, about 6 more minutes. Uncover and stir in the beans and all but 2 tablespoons of the cilantro; continue simmering until the spaghetti is tender and most of the liquid is absorbed, about 3 more minutes. Divide the pasta and beans among bowls and top with the remaining cilantro and the cheese.
