Any meal comprised of chicken as a main ingredient, with several other ingredients thrown together to make a meal. This usually occurs when one is cleaning out their refrigerator.
Husband: Honey, what's for dinner?
Wife: I was cleaning out the fridge and I found some chicken in there. I threw it in the crockpot for a few hours with some other leftovers
Husband: So what the hell is for dinner?
Wife: Chicken! HELLO?!?!
And that's when "chicken hello" was born.
