My grandmother (in OKC) made - in addition to many of the foods already listed - the best chicken and dumplings
ever. She also made incredible homemade biscuits, and she put gravy on everything. Breakfast, lunch, dinner - didn't matter. She had a gravy for it.
Lots of vegetables - especially things she could grow and can. Green beans, potatoes, sweet potatoes (*shudders*) carrots, cucumbers, and probably a bunch of others I'm forgetting.
The Kents are of a later generation than my grandparents, but I suspect some of these foods are still standard fare in the Midwest. They certainly are here in the South, where I live
.
