@heartofcoyote you just cook rice (this is why people have a good rice cooker so they can keep the dinner rice for breakfast overnight in it and it’ll still be fresh)

We have dozens of rice types for breakfast with different sides. Curry rice, coconut rice, rice rolls, rice cakes.. breakfast fried rice
