In a large skillet or pan, cook the chopped bacon over medium heat until it becomes crispy. Remove the bacon with a slotted spoon and set it aside, leaving the bacon grease in the pan.

Add the diced onion to the bacon grease in the pan and cook until it becomes translucent, about 3-5 minutes. Add the minced garlic and cook for another minute until fragrant.

Add the chopped cabbage to the pan, stirring to combine with the onions and garlic. Cook for about 10-15 minutes, stirring occasionally, until the cabbage is tender and slightly caramelized.

Season with salt, pepper, and red pepper flakes if desired. Stir in the cooked bacon.
