Probably Fair food would (as in County Fair.) Provided they haven’t all changed since I was a kid. (Having not been to a Fair since childhood, I wouldn’t know. Hence, its validity as an answer.) So, anything inappropriately breaded and deep-fried.

I’ve never run across home-cooking or home style cooking that was close enough to my mother’s to trigger nostalgia. (Though I guess tuna-mac recalls undergrad years lean on time and money, but with a youthful propensity to not worry over the waistline.)
