What is the unhappiest food?

See title: I have spent dozens and dozens of hours making amazing food in this game. Maxed out nutrition and happiness stews, burritos, sandwiches, fried chicken roasts, you name it. The possibilities are endless, and there are many, many threads and posts about it.

But what I want to know is, what is the WORST food in the game? In before "bleach lol" or any other poison. I'm not talking about something you can consume that would kill you. I want to know what the SADDEST, LEAST DELICIOUS food there is in this game.

Is it a raw roach? A burnt stir fry of four roaches? A cold/burnt TV dinner?

What food could I feed my avatar that would send them spiraling into a well of depression? What is the Most Unhappy Food?
