copying another comment asking about Caribbean dishes

dumplings, plantians, peas and rice, hibiscus sweet tea (it had a specific name i dont remember i drank so much as a kid), guava duff jerk chicken, beef patties, curry chicken (the best meal in the entire world, we make it better than anyone else ill fight you in a parking lot, i dont eat meat anymore so I use soy curls or make curry chickpeas), oxtail is extremely popular, steamed chicken, and our national pride conch eat it fried or in salad but its not gonna taste good unless its fresh and im pretty sure florida has the only good conch in America. although climate change and over fishing is ruining that too i hear. also they marinate the fried chicken in this sauce i cant describe but its the best friend chicken in the world. you can veganize most things its about the spices.

as for black southern food try collard greens, mac and cheese, candied yams, fried mushrooms, okra, grits (not sure how that would be vegan, use LOTS of vegan butter) cornbread, black eyed peas, and sweet potato pie. im blessed to be surrounded by black vegan restaurants if you are too you MUST go. i command you.
also i cant recommend any african foods because i dont cook any (yet) i just go to this vegan Ethiopian place and order a little of everything and make my partner eat anything I dont like lol.
