For Two
Preheat the oven to 375°F and grease a casserole dish if using one with avocado oil.
Preheat a large skillet to medium high heat and add 1 tbsp avocado oil.
Add the onions and mushrooms and saute for 3-5 minutes. Add spinach and cook for 1-2 minutes.
Turn the heat down to medium and add in the cream, cream cheese, mayo, mustard, garlic, Parmesan cheese and combine using a spoon until mixed.
Add the cooked and chopped bacon, salt & pepper and the chicken. Mix to combine.
You can now transfer the contents to a casserole dish if you are not using an over safe skillet.
Spread mozzarella cheese on top and bake for 5 minutes and then broil for 2-3 minutes.
