Heat oil in a medium saute pan. Add garlic, onion, carrot, celery and mushrooms. Sauté until onions are softened and mushrooms are lightly browned, about 3 to 4 minutes. Add quinoa and turmeric and continue sauteing for 2 more minutes to toast quinoa. Transfer quinoa mixture to rice cooker. Add red bell pepper and broth. Cook on “white rice” setting.
Toss to loosen up quinoa.
Quinoa has a bitter coating called saponin that needs to be washed off before cooking. Briefly soaking and then rinsing quinoa before cooking removes this coating.
