Over medium heat in a small sauce pan, heat bone broth to a simmer. Add dried mushrooms, turn off heat and let rehydrate for 2-3 minutes or until mushrooms are soft. Strain broth (using fine mesh strainer to remove any debris from the mushrooms) reserving both the mushrooms and broth separately. Coarsely chop rehydrated mushrooms, set aside.
Preheat oven to 350, grease a 9x9 casserole dish.
Rinse noodles throughly with warm water. If desired, coarsely chop into bite sized pieces.
Open the pork rind bag to remove air, crush the pork rinds in the bag by smooshing the bag.
Drain tuna, discarding oil. (I suggest giving it to your dog or cat on their food, it's delicious and healthy for them)
