Cook the pasta according to package direction. Add in the frozen corn about 1-2 minutes before the pasta is done.
Drain the pasta and rinse it with cold water.
Meanwhile, drain and rinse one cup of black beans. Chop up assorted sweet peppers (I used miniature ones, but if you'd rather use just one large one, that works as well). Halve the cherry tomatoes.
Finely chop up the red onion and cilantro.
Stir together the pasta, corn, black beans, sweet peppers, cherry tomatoes, onion and cilantro.
In a resealable jar combine all of the dressing ingredients. Shake until combined. Pour the dressing over the pasta and vegetables. Stir to combine. (you may not want to use all the dressing- so add it slowly)
