The proper way to eat this is to pour the sauce on as you eat, but since that's a bit troublesome, I just mixed it all together! All it is is bean sprouts and beef, but it's delicious!
I tried making mixed rice with bean sprouts and it turned out delicious!
Did you adjust the amount of water? The bean sprouts will let out some moisture, so toss out a bit of the water! If you like spicy foods, try adding some powdered red chili pepper.
