For the quinoa, heat oil over medium heat in a sauce pan with ginger, stirring until fragrant. Add (uncooked) quinoa and stir until lightly toasted, about a minute. Add water and salt and bring to a boil. Cover and reduce heat, simmer for 10 minutes or until quinoa is tender and water is absorbed. Remove from heat and stir in the baby bok choy and green onions, cover and set aside to allow to wilt.
While the quinoa is cooking poach the salmon – in a large skillet, bring the water, red pepper flakes and ginger to a boil. Add salmon, cover and poach for 5 minutes or until cooked throughout (add ¼ cup more water if needed, do not let evaporate completely). Transfer salmon to a plate, and finish making the glaze using the remaining poaching liquid.
For the glaze, add the remaining ingredients to the skillet and stir until combined and slightly reduced.
To serve, place the salmon on a bed of the quinoa mixture and drizzle with the glaze.
