Combine the quinoa and water in a small saucepan and bring to a boil. Reduce the heat and simmer, with the lid slightly ajar, for 15 minutes, or until fluffy. Remove from the heat and cool completely.
Meanwhile, in a large salad bowl, combine the carrots, beets, red onion and parsley. Stir in the cooked quinoa.
In a small bowl, whisk together the lemon juice, olive oil and sea salt to taste until emulsified.
Pour the dressing over the salad, top with pea sprouts and serve immediately. Alternatively, you can store the salad (with the dressing) in the fridge until ready to serve, then top with pea sprouts.
