For whatever nonsensical reason (aliens, kidnappers, massive food shortages, deity of your choice comes down and makes it so), you’ve been told you can only eat one food for the rest of your life. Once you make your decision, there is no changing it. Ever.
What food would you pick if you could only eat one for the rest of your life?
No doubt I would die of mercury poisoning, but I’d go with sushi.
I actually thought of this one. I have to go with oatmeal. And now I send gratitude to the universe that I don’t have to choose!
