01 - Combine quinoa and water in a medium saucepan. Bring to a boil, then reduce heat to low, cover, and simmer for 12–15 minutes until all water is absorbed. Remove from heat and fluff with a fork. Allow to cool slightly while preparing remaining components.
02 - Preheat grill or grill pan over medium-high heat. Brush pear halves with olive oil. Place pears cut side down on the grill and cook for 2–3 minutes until distinct grill marks appear and fruit is slightly softened. Remove from grill and slice into wedges.
03 - Heat a dry skillet over medium heat. Add chopped walnuts and toast for 2–3 minutes, stirring frequently, until fragrant and lightly golden. Transfer to a plate to cool completely.
04 - In a small bowl, whisk together extra virgin olive oil, honey, lemon juice, and Dijon mustard until fully emulsified. Season with salt and freshly ground black pepper to taste. Set aside until assembly.
05 - In a large salad bowl, combine cooled quinoa, mixed salad greens, sliced red onion, dried cranberries, toasted walnuts, and crumbled feta cheese if using. Drizzle with honey-lemon vinaigrette and toss gently to evenly distribute all components.
06 - Arrange grilled pear wedges over the top of the salad. Serve immediately while pears are still slightly warm and quinoa retains its texture.
