Heat a large, non-stick skillet over medium heat. No oil is needed.
Once the skillet is hot, sprinkle the shredded mozzarella in an even layer to completely cover the bottom of the pan.
Allow the cheese to melt and begin to bubble, which should take about 3-4 minutes.
Evenly sprinkle the garlic seasoning and Italian herbs over the bubbling cheese, then top with the chopped pepperoni.
Continue to cook until the edges are deep golden-brown and crispy, and the pizza easily slides around in the pan. This will take another 4-6 minutes.
Carefully slide the finished pizza onto a cutting board or serving plate.
Let it cool for a minute before slicing and serving.
