I have some leftover burger patties and chicken from a couple days ago so I plan to have some leftovers. But I keep a well stocked freezer and dry pantry too. Right now what I am working on making is chicken pot pie filling, the chicken meat and broth is from a leftover slow long cooked Costco chicken. I make the filling and freeze it, and keep crusts in the fridge most of the time so it’s really easy to assemble.
