Rice Cooker Method: Cook brown rice and red quinoa in the rice cooker at the same time on the white rice setting and water measurement line. Stovetop Method: In a saucepan. Bring 4 cups water and a large pinch of salt to a boil. Add the rice, lower the heat, and cover the pan. Simmer for 20 minutes (it will not be tender). Tip the quinoa into the rice, re-cover the pan, and continue cooking for 20 minutes, or until the rice and quinoa are both tender. Total simmering time is 40 minutes. This step can be done the day before, using cold rice is a great idea!
