Scientifically, the egg. Fish lay eggs, and on an evolutionary level, they evolved earlier than birds (which evolved from amphibians then reptiles).

Therefore, the first egg came before the first chicken.

But in terms of food, the egg as well! You eat fried eggs in the morning before you eat fried chicken for dinner, right?
