Cut chicken thighs into 1 - 1 1/2" bite-size chunks. Transfer to a large bowl. Add half of the avocado oil, arrowroot, salt, and pepper. Give everything a nice stir and be sure it is evenly coated. Set aside.

Heat up a large skillet over medium heat for 2 minutes and add the oil. Let that heat through for another minute. Add chicken to the pan, and cook for 4-5 minutes each side until golden brown but not completely cooked through. Do so in a single layer (make sure you do not crowd the pan. You may need to cook in batches!) Transfer to a bowl or plate with a slotted spoon and set aside.

Add the diced onion to the pan and cook for 2-3 minutes until soft. Add 1 tablespoon of oil from the sun dried tomatoes and minced garlic. Cook for 1 minute, stirring often. Add broth to the pan, scraping from the bottom of the pan and stirring frequently. Cook until broth has reduced down by at least 50%.

Add sun-dried tomatoes to the pan. Fry for 2-3 minutes until quite fragrant and well combined, stirring occasionally.

Add coconut milk and nutritional yeast to the pan. Once the coconut milk has reached a boil, turn the heat down to medium-low. Add spinach to the pan and stir until slightly wilted, about 1 minute.

Add chicken back into the pan and sprinkle with seasoning. Stir frequently for another 7-10 minutes, letting all of the flavors marinade and allowing the chicken to cook all the way through. Season with additional salt and pepper if necessary.

Top off with fresh lemon wedges and chopped parsley.
