Add 2 cups of rice to your rice cooker pot, rinse thoroughly, then drain and return the rice to the pot.
Add the Chinese sausage links, shiitake mushrooms, chopped onions, frozen corn, soy sauce, chicken bouillon, and oyster sauce.
Select the "White Rice" setting on your rice cooker and let it cook.
Once done, sprinkle in chopped green onions and give everything a good mix.
For a fun presentation, pack the rice into a small bowl to mold it, then flip it onto a plate.
Enjoy your flavorful, one-pot rice dish!
