Chicken, potatoes, celery, onion, carrots, parsley, salt, pepper. NO PEAS.
Get a large roaster, cook, cool, remove meat from the bones. Save some breast or dark meat for another meal.
Use the broth, add flour to thicken into gravy and use to cook the veggies, add cut up meat. Pour hot into prepared pie crust. Made from scratch of course!
Cover with another crust and bake.
Also freezes well before cooking.
Makes a lot so plan to freeze some.
My daughter has been known to use a cooked rotisserie chicken and a jar of chicken gravy or 2!

And frozen pie crust. Same veggie as above.
