California vs. Indiana

It should be noted that I was raised in a home that I would consider culturally Californian. My mom was always very health conscious about the food she made for dinner; meat was always lean, there were always at least two or more types of vegetables, and usually no more than one carb dish.
Needless to say my biggest culture shock wasn't France or Norway or Sweden. My biggest culture shock was Indiana, and the shock was entirely food-based.

Which leads to last night.

Last night Wil generously decided he would cook me dinner so I would have more time to focus on studying for mid-terms. Wil is from Indiana.

The resulting conversation:

Me: "What is this?"
Wil: "Chicken and rice and mashed potatoes."
Me: *looks confused*
Wil: "What? You like my chicken and rice."
Me: "Yes. But why mashed potatoes?"
Wil: "Don't you like mashed potatoes?"
Me: "Yes. But we already have rice. We can't have potatoes AND rice."
Wil: "Why not?"
Me: "Because, that's two carb-based dishes. You can't have two carb-based dishes in one meal. It's unnatural. It's like having more than one type of meat in a meal."
Wil: "See, this is why you had issues in Indiana. In Indiana, potatoes and rice are a perfectly acceptable combination. Only in California would they have any issues."
Me: "But it doesn't make any sense!"
Wil: "Fine. Mix them together; that way you have one carb-based dish."
Me: "That's cheating! Hoosier!"
Wil: "It works. Hippie."
