In a large skillet, cook the bacon over medium heat until crisp. Remove bacon and set aside, leaving the fat in the skillet.

Add the vegetable oil to the skillet and increase the heat to medium-high. Add the onion and garlic, sautéing until translucent.

Add the shredded cabbage to the skillet, stirring to mix it with the onion and garlic. Cook until the cabbage is wilted and begins to brown at the edges.

Sprinkle the apple cider vinegar and sugar over the cabbage. Season with salt and pepper to taste. Cook for an additional 2-3 minutes, stirring frequently.

Return the bacon to the skillet, mixing it with the cabbage. Cook for another 2 minutes, or until everything is heated through and combined.
