Bring a large pot of water to a boil and cook pasta according to package instructions. Once it's done, move to a strainer, rinse under cool water and drain.

In a large bowl, add all the dressing ingredients, including fresh-squeezed juice from two limes, and mix until smooth.

Add the drained pasta, black beans, corn, spinach and cilantro to the bowl with the dressing and stir until well combined. Taste and add more salt, pepper or extra lime juice to your liking.

You can serve immediately or chill for a couple hours first.
