Preheat your oven to 350°F (175°C) to ensure the pie bakes evenly.
Place your unbaked pie shell in the pie dish.
In a large mixing bowl, whisk together the eggs until well beaten. Add granulated sugar, light corn syrup, salt, vanilla extract, and melted margarine. Whisk until fully combined and smooth.
Stir in the pecans and semi-sweet chocolate chips, ensuring they are evenly distributed.
Carefully pour the filling mixture into the prepared pie shell, ensuring it is evenly spread.
Bake for 60-70 minutes, or until the filling is set and the top is golden brown. A knife inserted in the center should come out clean.
Let the pie cool for at least 2 hours before slicing.
