Cook the quinoa according to taste. For this recipe, I like to cook my quinoa with chicken broth. Also brown the ground chicken if you want a quicker cook time. You can cook these two items ahead of time, if you like.
Pre-heat the oven to 350 degrees.
Meanwhile, finely grate the red onion, one bell pepper, and ginger root. Grate these items directly into a bowl to capture all of the juices. Mince the garlic, and finely chop the mushrooms.
Make the spice mixture and the sauce, set aside.
Note: You don't have to make the spice blend like I did. You can find a 5-spice powder blend products at your local grocery store that will have these ingredients.
Cook the onion, garlic, ginger, pepper, and mushroom for 2-3 minutes. Start with the onion, cook for about 30 seconds and then add the ginger and garlic. Cook for another 30 seconds to one minute, then add the peppers; cook down for another minute before adding the mushrooms.
Once the chicken is browned and the quinoa is cooked, mix in a large bowl with the prepped ingredients, minus the sauce. When combined well, stuff the bell peppers and top with the sauce.
Bake uncovered for 20-30 minutes until peppers are tender.
Note: If you do not want to brown the ground chicken before combining, bake the peppers covered for 60-70 minutes.
