In a shallow pan, on medium heat, melt 1 tablespoon butter and add 1 tablespoon of olive oil. Add the red onion and cook it until its lightly browned, 10-15 minutes. Remove the onion from the pan and set aside.
Add the remaining the butter and olive oil, then add the red cabbage. Allow the cabbage to cook down and brown, approximately 15-20 minutes.
Reduce the heat, add the brown sugar, balsamic vinegar, garlic powder, dried oregano, cayenne pepper, salt and pepper mix and cook for another 5-10 minutes before adding the cooked red onion.
Cook for a further 5 minutes, on low heat to allow the flavours and vegetables to combine. Remove from heat and serve warm. Enjoy!
