Bistek for Baon

Nowadays, I try to think up meals that I can cook in the morning (without rushing too much) so that they'd still be hot by lunchtime, thanks to our lunch bag that keeps meals hot for 4-6 hours. It's from Biokips. I don't like nuking my meals anymore as they tend to dry up.

Here's one of those quick meals. I'm sure most of you already know how to cook this but for those newbies, here goes. Saute some onion rings in oil. Fry some sukiyaki cut beef for about 30 seconds on medium heat. Pour the soy sauce-calamansi mixture and simmer. Pour on rice or pack in a separate container. I poured this on the rice to make the rice yummy by lunchtime.
