Prepare your pizza crust according to directions.
Do the first initial bake without toppings at the recommended time for that crust.
When the par-baked naked pizza crust comes out, top with the barbecue sauce, brush across or spread with a spatula in a thin layer (you can go light or heavy here, it's a personal preference).
Topp with the shredded cheese, if using.
Next add the shredded kalua pork, evenly dispersing it across the cross.
Top with the thinly sliced red onion.
For most pizza crusts continue to bake with the toppings at the temperature suggested, for approximately 10-15 minutes.
425ºF for the cassava flour and the cauliflower crusts.
350ºF for the Simple Mills Grain-free crust.
Bake until the pizza crust is baked through and to your liking, the cheese is melted and the toppings are warmed through.
Remove from the oven, sprinkle with green onions and a pinch of the Hawaiian Alaean Salt, slice and enjoy.
