Place the quinoa in a strainer and rinse thoroughly with cold water. Let drain. Bring 1-1/2 cups water to a boil, add the quinoa and stir. Bring to a boil again, lower the heat and simmer, covered, for about 15 minutes, or until all the liquid has been absorbed and the grains are tender. Remove the pan from the heat and spoon the quinoa into a bowl to cool. Add the kiwi fruit, mango, cashews, mint, ginger and cumin and toss ingredients to distribute them evenly. Mix the lemon juice and olive oil together and pour over the salad. Toss. Let rest for 15 minutes. Taste for seasoning and add salt and pepper to taste.
