In a large cast-iron skillet or a large pot, heat chopped bacon over medium heat until crispy.
Once your bacon is done, set aside and toss in a chopped yellow onion into the bacon drippings and sauté until golden.
Stir in fresh garlic, stirring it to let the flavors meld together on medium heat.
Once your garlic is nice and aromatic, stir in the stone ground mustard, brown sugar, and red pepper flakes.
Next, add chunks of green cabbage to the skillet and season to taste with Cajun seasoning.
Stir in water and chicken bouillon and scrape the bottom of the pan to deglaze. Continue cooking over medium-high heat until it's tender.
Once cabbage is tender and the moisture has reduced, stir in the crispy back pieces.
Season the whole thing with Cajun seasoning, salt and pepper to taste.
Serve warm.
