In a medium pot, combine the rinsed quinoa and vegetable broth (or water). Bring to a boil over medium-high heat.
Once boiling, reduce the heat to low, cover, and simmer for 15 minutes or until the quinoa is fluffy and the liquid is absorbed.
Remove from heat and let the quinoa cool for about 10 minutes.
In a large mixing bowl, combine the black beans, diced red bell pepper, corn, avocado, red onion, and chopped cilantro.
Add the cooked quinoa to the mixing bowl.
In a small bowl, whisk together the olive oil, lime juice, cumin, salt, and pepper until well combined.
Drizzle the dressing over the salad and gently toss everything together until evenly coated.
Taste and adjust salt or lime juice as desired.
Chill the salad in the refrigerator for at least 30 minutes to allow the flavors to meld.
Notes
Serve the salad in a large bowl, garnished with extra cilantro and lime wedges for a fresh look. For individual servings, layer in mason jars to showcase the vibrant colors.
