Preheat the Solo Stove Pi Pizza Oven to 600 degrees.
Brush your store-bought crust all over with olive oil.
Spread marinara sauce on top of crust. You will not need the whole jar of it, just enough to cover the pizza crust.
Sprinkle the cheese on top of the sauce and add in pepperoni.
Sprinkle with more cheese on top of the pepperoni, if desired, and top with pizza seasoning and red pepper flakes.
Bake in wood fired pi pizza oven for 3-5 minutes. Ours took about 3 minutes total.
Remove from pizza oven, sprinkle with grated parmesan, slice and serve!
