Preheat the oven to 375°F and grease a casserole dish if using one with coconut oil spray.
Preheat a large (cast iron) skillet to medium high heat and add 1 tbsp coconut oil.
Add the onions and mushrooms and saute for 3-5 minutes until tender. Add the spinach and cook for 1-2 minutes until wilted down.
Turn the heat down to medium and add in the cream, cream cheese, mayo, mustard, garlic and cheddar cheese and combine using a spoon until fully incorporated.
Add in the cooked and chopped bacon, seasonings and the chicken. Stir to combine.
At this point either transfer the entire skillet contents to a casserole dish if you are not using an over safe cast iron skillet.
Top the casserole with mozzarella cheese and bake for 10 minutes and then broil for 2-3 minutes.
Serve immediately!
Best stored in an air tight container in the fridge up to 5 days.
