In a medium saucepan, combine quinoa and vegetable broth (or water). Bring to a boil over high heat, then reduce to a simmer. Cover and cook for about 15 minutes or until liquid is absorbed and quinoa is fluffy. Remove from heat and let cool slightly.
In a large mixing bowl, combine black beans, corn, red bell pepper, avocado, cherry tomatoes, red onion, and cilantro.
In a small bowl, whisk together lime juice, olive oil, cumin, chili powder, salt, and pepper.
Once quinoa has cooled, add it to the mixing bowl with the vegetables. Pour the dressing over the salad and toss gently until everything is well combined.
Adjust seasoning with more salt or lime juice, if needed.
Serve immediately or chill in the refrigerator for about 30 minutes to enhance the flavors.
Notes
Serve the salad in a large bowl or individual plates, garnished with extra cilantro and lime wedges for a vibrant touch.
