Preheat oven to 350°.
Grease bottom of a 9x13" pan with butter or cooking spray.
Combine pumpkin, evaporated milk, eggs, sugar, cinnamon, and salt in a large bowl.
Pour the mixture into your 9x13" pan.
Sprinkle dry cake mix over pumpkin mixture - it will completely cover the top.
Top with pecans and drizzle melted butter over the pecans.
Bake for 50-55 minutes or until golden and tasty!
Cool...chill...and serve chilled (if you can, but frankly, we almost always dig in long before it is chilled!).
Add a dollop of whipped topping as garnish for the fun of it! (totally optional, but super festive!)
