Heat 1–2 teaspoons of neutral oil in a large skillet or Dutch oven over medium heat. Add the sliced andouille sausage and cook until browned, about 4–5 minutes. Remove the sausage from the pan and set aside.
Add the diced onion and bell peppers to the pan and cook until softened, about 4–5 minutes.
Add the ground beef to the pan with the vegetables. Break it apart with a spoon and cook until browned and fully cooked through.
Sprinkle in the Cajun seasoning, kosher salt, black pepper, granulated garlic, and granulated onion. Stir well to evenly coat the meat and vegetables.
Add the chopped cabbage and toss everything together until combined. Cover and cook for 10–12 minutes, stirring occasionally, until the cabbage is tender.
About halfway through cooking the cabbage, return the browned sausage to the pan and stir to combine. Continue cooking until the cabbage reaches your desired tenderness. Serve hot.
