01 - Set oven to 350°F (175°C) and grease an 8-inch baking pan or line a baking sheet with parchment paper.
02 - In a mixing bowl, combine cornmeal, flour, sugar, baking powder, baking soda, and salt. In a separate bowl, whisk together buttermilk, egg, and melted butter. Fold wet ingredients into dry until just combined. Transfer batter to the prepared pan and bake for 15–18 minutes until golden and set. Allow to cool, then crumble 1 cup for filling.
03 - Heat olive oil in a skillet over medium. Add celery, red bell pepper, green onions, and minced garlic; sauté for 3–4 minutes until vegetables are softened. Remove from heat.
04 - In a large mixing bowl, combine lump crab meat, crumbled cornbread, sautéed vegetables, mayonnaise, Cajun seasoning, lemon juice, cayenne (if using), chopped parsley, salt, and black pepper. Blend gently to retain crab texture.
05 - Slice rolls lengthwise without cutting through entirely. Hollow out some bread from the center to make space for the filling.
06 - Generously fill each roll with the crab-cornbread mixture. Place rolls on the prepared baking dish or sheet.
07 - Brush tops of the rolls with melted butter to ensure a golden finish.
08 - Bake stuffed rolls at 350°F (175°C) for 10–12 minutes, until rolls are golden brown and dressing is heated through.
09 - Serve warm, garnished with additional fresh parsley if desired.
