This bright, crunchy and hearty quinoa salad is inspired by the flavors and textures of tabbouleh and Greek salad. Quinoa, cucumbers, bell pepper, olives, lots of parsley and an assertive lemon-garlic dressing make it a filling and protein-rich vegan lunch, or a great side for grilled chicken, seared fish or spiced chickpeas. Feel free to add other briny, creamy, snappy or herbaceous ingredients, such as feta, avocado, torn romaine leaves or fresh mint. The salad will keep for up to 2 days refrigerated; refresh with salt and lemon juice before eating as flavors may become muted in the fridge.
