Two days ahead:
Day 1: Rinse and soak the quinoa overnight in enough water to cover it.
Day 2: Drain and rinse the quinoa several times throughout the day. This should be done in a sieve so the quinoa doesn’t sour. Leave the quinoa in sieve (placed in a large bowl) in between rinses.
Day 3: Make the dressing by whisking together the lemon juice, garlic, olive oil, salt and pepper. Combine the quinoa sprouts, tomatoes, mint, parsley and dressing.
