Rice and eggs are the start of a million meals. You can toss veggies (whatever you like) in whatever sauce (soy, hoisin, teriyaki, oyster, etc) and throw it with the rice. You can add broth. You can add crunchy garlic or green onions.

Learn to hard boil eggs and you can marinade de-shelled ones for a few days in soy/onion/chilis and it pairs with it as well.

Our Asian supermarket has very large bags of Bok Choy for cheap, and that can be made in a ton of ways.
