Frozen rice is your friend. I know it sounds surprising, being from the Philippines where freshly cooked rice is the meal standard but in bentoland, having ready cooked rice in the mornings is a big speed boost. And when you don’t have leftover rice from the night before, taking some from your frozen stash then nuking on high in the microwave works just as well.
In this case, instead of simply freezing the rice, I added leftover chopped bistek tagalog, then molded the rice into onigiri triangle shapes then froze. Then, I simply peeled off the plastic wrap, microwaved on high, then rewrapped in plastic wrap for easier handling. To go with it, I fried some chicken nuggets and reheated some frozen peas, corn & carrots.
As long as it’s something that won’t perish from freezing (like cream cheese) or microwaving (still cream cheese), it’s pretty safe mix with your rice to freeze as onigiri. The nice thing is, it also works as a quick filling snack since it’s rice plus other yummy tidbits. Other than bistek, I’ve also tried adobo flakes, tapa and SPAM and they all turned out yummy. If you were to make some, what would you add?
