FOOD FOR THOUGHT

[cannongal]

 warm tuna sounds gross. 

Brain conditioning.   If you've only ever eaten tuna salad as a cold sandwich,  the idea of it being hot is going to sound and taste gross to you.   Not to mention that we've all been told since birth that warm mayonnaise leads to food poisoning. 

Iceburg, or any type of lettuce is another example,   most people use it as a base for a cold salad,  so the idea of frying it up and using it as a side dish would sound gross to most people.   Not the Chinese tho,  those guys put fried lettuce in everything.   Most people don't realize that the egg rolls they eat have fried lettuce in them.
