Preheat the oven to 420 °F and lightly spray a foil-lined baking sheet with nonstick spray.
Divide the dough into 4 equal balls.
On a lightly floured surface, roll each ball out into a circle about ¼" thick (think pizza. Pretend you're making a pizza crust)
Spoon the cheesesteak filling into the center of the dough circle
Sprinkle 1 ounce of cheese in the center of each dough circle
Roll the dough up like a burrito: Fold in the top and bottom, then roll over from the sides like a cigar.
Transfer the hot pockets to the prepared baking sheet.
You can lightly brush the rolled-up up dough with skim milk, as this will help it brown in the oven.
Bake for about 15 to 20 minutes, until the dough has browned up a bit.
