Place 1 cup quinoa in a fine mesh strainer and rinse under cold running water; drain briefly.
Put the rinsed quinoa in a large microwave‑safe bowl (big enough to hold about 3 cups cooked quinoa).
Add 2 cups water and, if using, a dash of salt and a dash of olive oil. Stir so the quinoa is fully submerged.
Cover the bowl with a microwave‑safe plate or a microwave cover.
Microwave on High for 6 minutes.
Using a kitchen towel or oven mitts to protect your hands, carefully remove the cover (watch for hot steam) and stir the quinoa.
Replace the cover and microwave on High for another 2 minutes.
Remove the bowl from the microwave (use a towel or mitts) and let it sit covered on the counter for 3–4 minutes to absorb remaining liquid; if water remains, wait a few more minutes.
Uncover and fluff the quinoa with a fork before serving.
Notes
Salt and olive oil are optional.
Use a bowl large enough to hold about 3 cups cooked quinoa.
