Easy way to cook quinoa (or brown rice) from: https://laughingspatula.com/how-to-oven-bake-quinoa-white-and-brown-rice/

Ingredients
1 cup quinoa, white or brown rice
2 cups water or broth
1 tablespoon butter or olive oil optional (I don't do this)
1/2 teaspoons salt
1/4 teaspoon pepper

Instructions
Preheat oven to 375 degrees
Heat 2 cups water or broth in microwave for 2 minutes. (I boil water like I am making tea not with my microwave).
Add quinoa (or rice) to 8 x 8 baking dish. (9 x 9 will work as well - really most of those tins are fine).
Pour hot liquid over the grain.
Add salt, pepper and butter if using (I don't use butter but do add other spices if I am serving it as is, otherwise, I don't if I am using it in a salad (see quinoa salad) or frying some vegis separately to mix in).
Cover tightly with foil
Bake quinoa or white rice for 25 minutes.
Bake brown rice for one hour.
Remove - LET REST 5 MINUTES.
Carefully remove foil - its hot in there!
Serve!
