In a skillet, fry the potatoes in coconut oil over medium heat until the potatoes are cooked through and golden brown. This will take about 25 minutes. Sprinkle the garlic salt on top of the potatoes at some point while they are frying.
Once the potatoes are cooked through, remove the skillet from the heat and add the pizza sauce, cheese, pepperoni, sausage, peppers and any other toppings you wish.
Set the oven to broil on high. Put the oven rack on the highest level it will go and place the skillet on the rack. Broil for 3-5 minutes or until the cheese is golden brown. Watch carefully while it is under the broiler.
