Cook the pasta in a large pot according to package directions until al dente, then drain and rinse under cold water.
While the pasta is cooking, prepare the vegetables and beans: chop the bell peppers, halve the cherry tomatoes, and finely chop the red onion and cilantro.
In a large bowl, combine the cooked pasta, black beans, corn, bell peppers, cherry tomatoes, onion, and cilantro.
In a separate small bowl, whisk together the olive oil, lime juice, cumin, salt, and pepper until well combined.
Pour the dressing over the pasta and vegetable mixture, tossing gently to combine.
Taste the salad and adjust seasoning as necessary, adding more salt, pepper, or lime juice to suit your preference.
Let the salad sit in the refrigerator for at least 30 minutes before serving to allow flavors to meld.
Serve chilled, garnished with additional cilantro or lime wedges if desired.
