Heat a large saute pan over medium high heat. Add 1 tbsp of the ghee. Season chicken pieces with salt and pepper. Once the pan is hot, add the chicken. Cook for 2-3 minutes per side until cooked through. Remove chicken from the pan and set aside.
Add the remaining tbsp of ghee into the same pan. Add frozen (or partially thawed) gnocchi and the mushrooms and cook on medium high heat 5-7 minutes until browned.
Add the chicken back into the pan along with the garlic powder, salt, and sage. Add spinach, stir to combine, and cook for an additional minute. Enjoy!
