Bring 2 cups of water and 1 cup of quinoa to a boil in a medium pot. Once boiling, lower heat, cover and simmer for 15-20 minutes until the quinoa is cooked and all of the water is absorbed.
Once done, remove from heat and let the quinoa sit.
To a blender, add salsa and diced tomatoes. Blend until smooth. [this step is optional - you can just mix together your salsa and diced tomatoes without blending them if you don't mind having a chunkier sauce]. Set aside.
Heat a cast iron skillet or oven safe sauté pan to medium heat and add olive oil, cubed chicken breasts, and half of the sea salt and pepper.
Cook, stirring occasionally, for about 10 minutes until chicken is cooked through.
Remove chicken and to the pan add bell peppers, onion, mushrooms, garlic, cumin, coriander, and the remaining black pepper and sea salt. Cook for 5-7 minutes.
Once veggies are tender, add cooked chicken, pinto beans, cooked quinoa and diced tomato/salsa mixture. Mix well.
Add shredded cheese on top and bake for 10 minutes.
Broil for another 3-5 minutes until cheese starts to brown.
Remove from oven and let cool for about 15 minutes before serving.
Serve with sliced avocado.
Enjoy!
Note: if you don't have an oven-safe sauté pan or cast iron skillet you can transfer the enchilada mixture to a baking dish before putting in the oven.
