Recently my boss (British guy) saw me eating chicken hearts with pasta at work during lunch. He was completely shocked, saying he had never thought of it as a normal meal.

In my country it’s totally okay (not a kind of everyday meal, maybe few times in a month but it’s not weird at all) I used to fry them in butter and a creamy garlic souse.

Is that really so weird for European or British people?
Do people find it’s disgusting or smth?
