In a large skillet, cook the chopped bacon over medium heat until crispy. Remove and set aside, leaving the drippings in the skillet.

In the same skillet, add the sliced onion and cook until translucent, about 5 minutes.

Add the minced garlic and cook for an additional minute until fragrant.

Stir in the chopped cabbage and cook for 10-15 minutes, stirring occasionally, until the cabbage is tender.

Return the cooked bacon to the skillet and mix well.

Season with salt, black pepper, and red pepper flakes. Drizzle with apple cider vinegar and stir to combine.

Cook for an additional 2 minutes, then serve hot.
