Rinse your quinoa thoroughly under cold water; I find this removes any bitterness and ensures a fluffy result. Combine the rinsed quinoa with vegetable broth in a medium pot and bring it to a boil over high heat. Once boiling, reduce the heat to low, cover the pot tightly, and let it simmer for 15 minutes. After simmering, turn off the heat and allow the quinoa to sit, still covered, for an additional 5 minutes to fully absorb any remaining liquid and steam.
While the quinoa finishes cooking and cools slightly, prepare your dressing. In a small bowl, whisk together the olive oil, freshly squeezed lemon juice, Dijon mustard, honey, and minced garlic. Season this vibrant dressing with salt and freshly ground black pepper. Simultaneously, slice your green scallions, chop the fresh parsley, and measure out the dried cranberries and slivered almonds, creating your mise en place for assembly.
Once the quinoa is ready, fluff it gently with a fork and transfer it to a large mixing bowl to cool completely – this prevents the feta from melting. Once cool, add the prepared green scallions, dried cranberries, slivered almonds, chopped fresh parsley, and crumbled feta cheese to the bowl. Pour the whisked dressing over the salad ingredients and toss everything together until evenly coated. I always taste and adjust the seasoning one last time here, adding a bit more salt or lemon if needed.
