Preheat your oven to 375 and lightly grease a 9x13 inch casserole dish.
Bring a pot of water to a boil and cook gluten free pasta 3-4 minutes less than the package calls for. For example, for the Jovial shells I cooked them for 8 minutes instead of 12. They will finish cooking in the oven!
Meanwhile, heat the ghee in a large skillet over medium heat. Add in the mushrooms, onion, and garlic. Sauté for 5-7 minutes until softened and the mushrooms have sweat off some of their liquid.
Pour in the sherry and stir.
Add in the chicken broth, thyme and salt. Bring the mixture to a boil then reduce heat to medium low. Let it simmer while you make the cashew cream.
Add the coconut milk, cashews, water, lemon juice (or ACV), and salt to a high powered blender. Blend on high for 1 minute or until the mixture is very smooth and creamy.
Pour the cashew cream into the pan and stir while cooking over medium heat. It should bubble and thicken after 1-2 minutes.
Add the peas and the drained tuna to the pan and stir.
Add the drained pasta to the pan and mix everything together. This can also be done right in the casserole dish!
Add the mixture to the casserole dish and top with Pork Panko (or crushed up chips or crackers).
Bake for 25 minutes until the sides are bubbling. Serve and enjoy!
