Add water quinoa and salt to pot, bring to a boil. Reduce, cover and simmer until water has been absorbed and quinoa tender (about 12-15 minutes). Scoop into a bowl and set aside to cool.
In a cup, or small bowl whisk together vinegar, oil, salt and pepper. Pour it on quinoa and add cucumber, green onions, parsley & mint. Mix well. Adjust seasonings as needed. Pairs nicely with grilled meat.
