2Heat a large, oven-safe skillet over medium heat. Add avocado oil. When it glistens, add the chopped onion and broccoli. Cover and cook, stirring occasionally, for 3-4 minutes to let the veggies soften.
3If the veggies appear too dry, add a splash of water or chicken broth.
4Stir in the chopped spinach, salt, pepper, chili powder, and pre-cooked chicken.
5Transfer chicken and veggie mixture to a casserole dish.
6In a bowl, whisk together the Greek yogurt and enchilada sauce, then pour over casserole dish.
7Top with cheese blend.
8Transfer to the oven and heat for 10–15 minutes or until the cheese is melted.
9Let it rest for 5 minutes, then top with cilantro, avocado, and jalapeno.
