Preheat the oven to 400 degrees F. Slice the half a head of cabbage into wedges. Brush each side with olive oil and sprinkle with 2 teaspoons of cajun seasoning. Place on the baking sheet.

Cut the smoked sausage into 4 sections and quarter the onion. Make small slits in the sausage pieces.

Add the sausage and onion to the sheet pan with the cabbage.

Bake for 20 minutes, then flip the ingredients and bake for an additional 10 minutes, or until the cabbage reaches your desired tenderness.

While baking, combine 1/4 cup mayo, 1.5 teaspoons cajun seasoning, 1-2 teaspoons hot sauce, 2 teaspoons chopped dill pickle, and 1 tbsp finely minced green onion in a small bowl to make a dipping sauce.
