Preheat the oven to 350 degrees.
Beat the eggs and sugar together with a whisk until the mixture is just a bit lighter. Just a minute or two.
Add the salt, corn syrup, and margarine and combine.
Add pecans and mix well.
Unroll your pie crust into a 9-inch pie plate or aluminum pan (use two aluminum pans stacked together for strength if you go that route)
Crimp or fold crust edges as desired.
Pour in the pecan mixture.
Bake until just set--about 50 minutes. Make sure it's not jiggling. If it is, bake it a few minutes longer and keep checking it every 5 minutes or so.
Check the crust at 20-25 minutes. If browning, cover just the crust with a ring of aluminum foil for the rest of the bake time.
