Food of Runeterra

I was wondering if any fabulous loreheads could help me find information about the food of different regions of Runeterra. I am an amateur cook and would love to compile a few recipes/cook book to emulate the food consumed in the various regions. Any information or where I can go to find more about what the denizens of Runeterra eat. Bonus points if I can learn the story behind the food and what it entails the respective cultures that eat it.

TIA.
