have you looked into southern cuisine? A lot of the cuisine of the south was invented by poor black folks and poor white folks due to limited resources and or slavery. You had to make do with what you had. This lead to good tasting but cheap to make food
Examples of southern cuisine
"A traditional Southern meal is pan-fried chicken, field peas (such as black-eyed peas), greens (such as collard greens, mustard greens, turnip greens, or poke sallet), mashed potatoes, cornbread or corn pone, sweet tea, and dessert—typically a pie (sweet potato, chess, shoofly, pecan, and peach are the most common)"
there's also soul food which includes more spices haha
Grits can be made with spinach, cheese, grilled onions etc. with a saucy meat. love some shrimp and grits.
Then of course you have louisiana/ missisipi basin cuisine. Also very good.
