Boil the carrots, celery, onions, and potatoes: Get out a large pot and toss into it the carrots, celery, onions, and potatoes.  Then put enough water into this pot so that it covers all of the veggies by about an inch.  Next place this pot on your stove top, over a high heat, letting everything come to a boil. Let it boil for about 15 minutes just so that the veggies are slightly cooked.

Preheat your oven to 350 degrees Fahrenheit

Assemble the pie: Get out your pie pan and grease it either with some butter, or a spray like pam.  Then place a few pieces of the phyllo dough, or one sheet of the homemade pie crust on the inside of the pie pan in order to make the bottom layer of the pie.  Then place in all of the veggies (including the frozen peas), and the turkey meat, and use a spoon to make sure that they are mixed together well. Then pour on the gravy until it covers everything, and again use a spoon to mix everything together.  Finally top everything with about 3 to 4 layers of the phyllo dough, or one sheet of the homemade pie crust. If you are using the phyllo dough then spray pam between each layer of the dough so that they stick together. At the end pinch together the bottom layer of pie crust/phyllo dough with the top layer so that it forms one nice package. *make sure to either work fast or keep the phyllo dough covered as it can dry out fast.  Also don’t worry if it breaks, just try to piece it all together and you will be just fine.

Bake the pie:  Take a knife and puncture 3 to 4 small slashes into the top center of the pie crust.  Then place the pie into your preheated oven and let it bake for about an hour. You will know that the pie is fully cooked when both the gravy begins to boil out of the slashes we made in the pie crust, and the top crust of the pie is browned to your liking.  Once the pie is done, take it out and let it rest for a minute or two.
