I usually note and I did not. Make sure you wash the quinoa very well. It has a natural chemical on it to make it bitter to birds so they will not eat the grains. It can be easily washed off. In large amounts this chemical is toxic to humans. When the water is no longer 'soapy' looking the Quinoa is free of this chemical. Note not of any real value but the soapy water? Makes great laundry detergent.
Make a vinaigrette by whisking together the lime juice, white pepper, jalapeno, and salt, then gradually adding the olive oil. Set aside.
Place the quinoa in a fine sieve and wash under running water, rubbing the quinoa with your hands, for a few minutes. Drain. In a pot large enough to hold the ingredients comfortably, combine 2 quarts of water and the cleaned and drained quinoa. Bring to the boil, lower the heat, and simmer, uncovered, for about 10 minutes, or until the quinoa is barely tender. Do not overcook.
Remove from the heat and pour through a strainer. Drain thoroughly, and let cool. (Do not rinse.).
Place the cooled quinoa in a serving bowl with the cucumber, tomato, scallions, parsley, and mint and toss. Add the reserved vinaigrette and toss again. Correct seasoning with extra salt and white pepper to taste, and serve.
