I used leftover lamb but you could use cooked chicken, tofu, etc., or quickly sauté chicken or ground beef for it.
If using uncooked meat add it to the skillet with the onions, etc.
Remember to keep unused / waiting phyllo sheets covered as they dry out quickly.
It’s easier to handle if you put the pie on a baking sheet before filling.
