The rainy-day-special-mega-beef-bowl challenge is the portal to the meat dimension, or that's what Persona 4's helpful dialog box tells you when your character attempts to take on this massive donburi (meat and vegetables surved over a bowl of rice). The clever cooks over at Gourmet Gaming made their own version of this collossal meal that you can attempt to make yourself.

Ingredients:

White rice

Beef

White onion

You can find the full recipe here. The challenge is actually an oversized bowl of gyudon, which is just beef and onion over rice. Gourmet Gaming added a few other ingredients to make this a slightly more colorful dish.
