Baked Ham and Cheese Rolls with Honey Mustard Sauce

0 If the pizza dough is refrigerated, take it out of the fridge 20 minutes before you begin so that it comes to room temperature (this will make it easier to work with).
10 Preheat oven to 400 degrees F. 
9 Spray an 8 x 8 baking dish with nonstick cooking spray.
2 Roll pizza dough out on a lightly floured surface into a rectangle that is roughly 16" x 8" (just use the baking dish as a guide, no need to be exact).
4 Top the pizza dough with ham and then with cheese each in a single layer with no slices overlapping.
5 Starting with the edge closest to you, roll the pizza dough up into a log so that the ham and cheese is on the inside. Use a serrated knife to slice the roll into 9 even pieces. Place the pieces in the prepared baking dish.
11 Bake the rolls, uncovered, until they are cooked through (use a knife to peel back one layer and check the center of a roll to insure it doesn't look doughy) and lightly golden on the top, 35 to 40 minutes. 
6 Heat butter in the microwave or on the stovetop until melted. Whisk the melted butter with mustard, honey, and poppy seeds.
12 Brush the honey mustard glaze evenly over the top of the rolls. 
7 Return the glazed rolls to the oven and bake until deep golden brown, about 10 minutes more. 
8 Serve rolls warm or at room temperature.
