Avocado1Cubed, ripe but firm
Cilantro1 cupChopped (optional, to taste)

For the Chili-Lime Vinaigrette

  • 1/4 cup olive oil
  • 1 tablespoon lime zest
  • 4 tablespoons fresh lime juice
  • 2 garlic cloves, minced
  • 1 teaspoon ground cumin
  • 1/2 teaspoon chili powder
  • 3/4 teaspoon kosher salt
  • 1/2 teaspoon honey or maple syrup (for vegan)

Step-by-Step Instructions

1. Cook the Quinoa

Start by thoroughly rinsing the quinoa under cold water to remove any bitterness. Combine 1 cup quinoa and 2 cups water in a medium pot. Add a pinch of salt, bring to a boil, then cover and reduce to a simmer. Cook for 14–15 minutes, or until the little tails of the quinoa emerge and the water is fully absorbed. Remove from heat and let rest for 10 minutes. Fluff gently with a fork and set aside to cool to room temperature.

2. Prepare the Dressing

In a small jar or bowl, combine the olive oil, lime zest, lime juice, minced garlic, cumin, chili powder, salt, and honey or maple syrup. Shake or whisk until well emulsified.

3. Chop and Assemble

  • Drain and rinse the black beans and corn.
  • Chop the peppers, tomatoes, scallions, red onion, and cilantro.
  • Dice or cube the avocado just before serving for maximum freshness.

4. Combine All Ingredients

In a large bowl, mix together the cooled quinoa, black beans, corn, peppers, jalapeño, cherry tomatoes, scallions, and red onion. Gently fold in the cubed avocado and fresh cilantro. Pour in about three-quarters of the chili-lime dressing and toss gently to combine. Reserve the remaining dressing for drizzling just before serving, if desired.

5. Serve and Savor

This salad can be served immediately, at room temperature, or chilled. The flavors deepen and meld after a few hours, so making it in advance works beautifully.

Tips for Perfect Southwestern Quinoa Salad

  • Rinse Your Quinoa: Always rinse thoroughly to remove saponins (bitter compounds on the surface).
  • Taste and Adjust: After tossing, adjust lime, salt, or spice to your liking.
  • Add avocado just before serving to keep it fresh and green.
  • Let it marinate: Chilling for a few hours allows flavors to meld more thoroughly.

Variations & Serving Suggestions

  • Add diced grilled chicken or shrimp for an omnivore variation.
  • Toss with crumbled cotija or feta cheese for extra creaminess.
  • Swap out black beans for pinto beans or even chickpeas.
  • Add diced mango or pineapple for a sweet, tangy contrast.
  • Serve with crunchy tortilla strips or over a bed of crisp romaine or butter lettuce.
  • Drizzle with hot sauce for extra heat.

Storage & Make-Ahead Tips

  • Refrigerate in an airtight container for up to 5 days.
  • For meal prep: Portion into individual containers for ready-to-go lunches. Keep avocado separate until ready to serve.
  • Great for potlucks, picnics, or weeknight dinners—just refresh with a little extra dressing when serving leftovers.
