This meat simmer is very convenient.
I've been making it ever since I've lived in Japan, and then freezing it for later use ♪
It's a bit sweet and salty, so if you combine it with some udon in light dashi stock, it'll taste just right. Also if you use it in fried rice, the flavor mixes into the rice and it'll become delicious.

Mixed ground meat is also OK.
When using in a bento, microwave on low for about 20 seconds to half-thaw. Then you won't need to cool it down when using. Recipe by TetoNZ
