All of the sides EXCEPT the potato salad, southern greens, and baked beans. Those have bacon. French fries, mac n cheese, black eyed pea salad, coleslaw, sliced bread, pickles... and all of the desserts. Also on Sundays they have waffles!
There are sides that can be eaten by vegetarians. The menu clearly marks any side made with pork with a pig symbol. However, there is no specific menu for vegan or vegetarian.
Honestly, I was focused on sampling the fare I was denied in Nashville because of the lines. There are several vegetable sides, like collards. Not sure if they would be considered vegan sides. So I would direct you to their menu at the website. Sorry.
