Preheat oven to 375°F. Spray a 9×13 (or larger) baking dish with nonstick cooking spray (I used avocado oil spray).
Combine all ingredients except cheese and toppings in prepared baking dish. Stir to combine.
Cover tightly with foil and bake for 45 minutes. Uncover, stir, and recover tightly. Continue to bake for another 45 minutes to 1 hour or until quinoa is fluffy and chicken is cooked through.
Uncover and sprinkle with cheese and bake for five minutes or until cheese is melted.
Serve with desired toppings.
Notes
If you want to add some color to this, feel free to use red bell peppers instead of green!This is great leftover, so it’s perfect for meal prepping to get ready for the week.
