I came across this while searching though instagram.
Can someone please help me identify the name of this food?
I see mushroom gravy but what is the yellow thing called and what is it made of?

オムライス デミグラスソース
オムライス - Wikipedia
Omelette w/ rice, in demi-glace sauce. The yellow-thing is egg. Looks fabulous, especially now that it is lunch time here in Japan...

That is "omuraisu" (from "omelet" and "rice").

The yellow is an omelet, so it is made from eggs.
