01 - Rinse quinoa thoroughly under cold running water to remove bitterness. Combine quinoa, water, and salt in a medium saucepan. Bring to a rolling boil, then reduce heat to low, cover, and simmer for 12 to 15 minutes until all liquid is absorbed and grains are tender. Remove from heat, fluff with a fork, and allow to cool completely.
02 - Preheat a grill or grill pan over medium-high heat. Lightly brush the cut sides of the nectarine halves with olive oil. Place cut side down on the grill and cook for 2 to 3 minutes until prominent grill marks develop and the fruit softens slightly. Remove from heat, let cool, then slice into wedges.
03 - In a large mixing bowl, whisk together the extra-virgin olive oil, honey, lime juice, lime zest, salt, and freshly ground black pepper until well emulsified.
04 - Add the cooled quinoa, diced red onion, cucumber, sliced chili, chopped mint, cilantro, and mixed salad greens to the bowl with the dressing. Toss gently until all ingredients are evenly coated.
05 - Carefully fold the grilled nectarine wedges into the salad, taking care not to break them apart.
06 - Transfer the salad to a serving platter or individual bowls. Sprinkle with crumbled feta cheese and roasted pumpkin seeds.
07 - Serve immediately at room temperature, or refrigerate for up to 2 hours before serving to allow flavors to meld.
