In a medium saucepan, combine the rinsed quinoa and vegetable broth. Bring to a rolling boil over medium heat. Once boiling, reduce heat to low, cover, and simmer for about 15 minutes or until quinoa is fluffy and liquid is absorbed. Remove from heat and let cool slightly.
In a large mixing bowl, combine black beans, halved cherry tomatoes, diced red bell pepper, finely chopped red onion, corn, and diced avocado. Stir to mix evenly.
Once quinoa has cooled to room temperature, add it to the mixing bowl with the combined ingredients. Gently fluff quinoa with a fork as you mix.
In a small bowl, whisk together the zest and juice of the lime, olive oil, ground cumin, chili powder, sea salt, and black pepper until well emulsified.
Drizzle the dressing over the salad mixture and toss gently to ensure every ingredient is well-coated.
Taste the salad and adjust seasoning, adding more salt, pepper, or lime juice as desired.
Let the salad sit for at least 15 minutes at room temperature to allow flavors to meld. Serve chilled or at room temperature.
