Cook the Quinoa
Rinse the quinoa under cold running water in your fine-mesh colander for about 30 seconds — this step isn’t optional. It removes the saponin coating that makes quinoa taste soapy and bitter. Combine the rinsed quinoa and water in a medium saucepan. Bring to a boil over medium-high heat, then reduce to a low simmer, cover, and cook for 13–15 minutes until all the water is absorbed. Remove from heat — don’t lift the lid — and let the quinoa steam, covered, for 5 full minutes. Fluff gently with a fork, then spread it out on a large rimmed baking sheet to cool to room temperature. This flat spread is the fastest cooling method and keeps the grains separate instead of clumped.

Toast the Pepitas
While the quinoa cooks, add the pumpkin seeds to a dry skillet over medium-low heat. Toast, stirring almost constantly, for 3–4 minutes until they’re golden, fragrant, and starting to pop lightly. The moment they smell nutty, pull them off the heat and transfer to a small bowl. They go from perfect to burnt fast, so stay close. Set aside to cool.

Make the Honey-Lime Dressing
Combine the olive oil, lime juice, honey, Dijon mustard, minced garlic, salt, and pepper in a small bowl or sealed mason jar. Whisk vigorously (or shake with the lid on) for about 30 seconds until the dressing looks slightly creamy and fully emulsified. Taste it — it should be bright, tangy, and just barely sweet. If it’s too sharp, add a drizzle more honey. If it needs more zing, squeeze in a little extra lime. Set aside.

Prep and Protect the Avocado
Wait until right before assembly to cut the avocado — this is the number one tip that keeps this salad beautiful. Halve, pit, and dice the avocados into ½-inch cubes. Immediately drizzle about 1 teaspoon of the prepared dressing over the avocado pieces and toss gently. The lime acid significantly slows browning, buying you at least 30–45 extra minutes of vibrant green color.

Assemble the Salad
Confirm the quinoa is fully at room temperature (not just “mostly cool” — warm quinoa will make the avocado mushy and dull the blueberries). Add the cooled quinoa to your large bowl. Add the blueberries, corn, soaked-and-drained red onion, feta, mint, and basil. Pour about ¾ of the dressing over the top and toss gently until everything is evenly coated. Taste — and add the remaining dressing if you want more brightness.

Finish and Serve
Fold in the diced avocado last with a gentle hand so the cubes stay intact and don’t smash into the quinoa. Scatter the toasted pepitas across the top right before serving — they need to stay dry to stay crunchy. Serve immediately in wide, shallow bowls for the best presentation of all those gorgeous colors.
