Combine the chopped or cubed onion, potato, and rutabaga with the pasty meat in a large bowl. Season with salt and pepper.
Lay one pie crust into a pie pan, pressing the bottom and sides down gently. Use a knife to remove excess crust from the edges.
Fill the pie pan with the meat mixture, evenly, not mounded.
Carefully lay the top pie crust on top. Use a knife again to remove excess crust.
Use your fingers to pinch the crusts together. Cut 4-5 slits in the top crust.
Bake at 350 for 1 hour.
Check the crusts half way through, you may want to add a thing strip of tinfoil to the outer crust to prevent burning.
