Rice cooker
Bought a nice one (zojirushi brand that has the little elephant), but I've read most rice cookers work well. I use it so often for different meals and it's been a game changer and money saver. Making rice is so simple now, and an easy cheap way to supplement a meal.
Rice eggs is a staple for us now: Make some rice, and when there's about 5 minutes left on time, throw in some scrambled eggs for a tasty protein.
