Preheat your oven to 220° C (425° F). Grease a 8 or 9 inch pie dish with butter.
To a mixing bowl, add the salmon, eggs, milk, butter, onion, parsley, basil, and salt.
Mix together with a spoon, the mixture will be quite thin compared to making a loaf.
Pour mixture into the prepared pie dish, I used a 9 inch dish for this.
Roll out your store bought crust or homemade crust, cut dough into a circle to a size that will fit the dish without going up the sides. Cut dough into 6 even pieces.
Place each piece on the salmon mixture to cover without overlapping.
Bake for 25 minutes then remove from oven.
Cut pie into 6 pieces, cutting the seams between each piece of crust. Serve, and enjoy.
