Prepare the quinoa: put it to a fine mesh strainer, rinse it under running cold water rubbing the seeds with each other with your fingers (for at least 1 minute) and drain well. Heat a drizzle of olive oil in a pot over a medium heat and fry the drained quinoa for about 1 minute till the rest of water evaporates. Add water, 0.25 tsp salt and bring to boil. Lower the heat and cook covered for approx. 15 minutes. Take it out from the heat and let it rest covered for 5 minutes more. Fluff the quinoa with a fork. The quinoa has to be dry, in case there is still some water left, transfer it to a strainer and let it drain completely.
