Take a round of biscuit dough, stuff with pepperoni and mozzarella cheese and seal the dough.
Brush olive oil over biscuit ball, and sprinkle Parmesan and dried oregano on each round.
Transfer biscuit balls into rice cooker, layering as you go. Add a bit more Parmesan and dried oregano as you layer.
Set rice cooker to cook. If your rice cooker has a timer, set it to 2 hours. If it doesn't have a timer, this will take 2 white rice cycles. Note: All rice cookers are different, so be sure to check your rice for done-ness.
Remove from rice cooker, turn over and out. Serve with marinara sauce.
