Feel free to add any extra veggies or proteins you want into this dish! If you want to add a bit of extra flavor or texture, try adding some fresh herbs such as thyme or parsley. Bacon pieces and bacon grease are also classic add-ins for a crockpot cabbage dish. Finally, add a pinch of red pepper flakes or cayenne pepper if you want some spice. You can add these ingredients at the start of cooking or sprinkle them on top (where appropriate) just before serving!
