Another vote here for rice. If possible, go for the "jasmine" variety, as it has a little bit of flavor already (Costco carries a good brand called "Super Lucky Elephant"). Strangely, the instructions on some rice packages say not to rinse it before cooking -- actually, you DO want to rinse it.
Best way to cook it:
1) Put rice into pan.
2) Rinse under cold water, moving the rice around and watching the starchy, white water build up. Drain off this water.
3) Repeat another 2 or 3 times.
4) Put in enough water so that when you put your middle finger straight down onto the top layer of the rice, the water level is to your first knuckle (roughly 1/2 inch).
5) Add a tiny, tiny bit of oil so the rice doesn't stick.
6) Cover and bring rice to a boil.
7) Once boiling, reduce heat to a simmer and keep covered. Check to see if a little more water is needed and try fluffing rice.
A great breakfast food is a couple of over-easy eggs and some fried rice. To cook the rice just take a frying pan, add some oil, crumble the rice into the pan and cook over medium heat uncovered. Add some garlic salt and freshly ground pepper and you are good to go! Cheap and easy.
