Add 1 tablespoon of the coconut oil to the saucepan. Add the shallot, celery and carrot and cook over low heat until softened, about 8 minutes. Add the quinoa and cook, stirring, for about 2 minutes. Add the stock, season with salt and pepper and bring to a boil. Cover and cook over low heat until the grains are tender and plump and the liquid is absorbed, about 18 minutes. Cover and let stand for 5 minutes.
