Rice? Generous splash of white vinegar into the rice cooker, then a pat of butter at the end to melt in the residual heat. If you want something to pair with stir fry, try drizzling with sesame oil instead.

Salad? Toss it with a splash of a good quality balsamic vinegar and extra virgin olive oil. Bonus points for tahini.
