This is my favorite way to construct the edges of a pie crust. It's easy, you don't have to trim anything and it looks rustic yet professional. Alls you do is press the crusts together, roll the edges inward, then take a knife and firmly score the roll at an angle, all around. Try it. It's better looking than pressing with a fork and easier to pull off than pinching.
This particular pot pie has homemade seitan plus the usual suspects; peas, carrots, shallots. I used the seitan simmering broth to make the gravy, so nothing was wasted. Except for, like, my entire afternoon.
