1. In a 5-quart Dutch oven or heavy-bottomed pot, heat oil over medium. Add flour, and cook, whisking constantly, until pale golden, 5 to 7 minutes. Stir in bell peppers, onion, garlic, and oregano; season with salt and pepper. Cook, stirring occasionally, until vegetables are crisp-tender, 10 to 12 minutes.

2. Add 4 cups water; stir in okra and sausage. Bring to a boil. Stir in shredded chicken, and warm through, 1 to 2 minutes. Season with salt and pepper; if desired, serve with cornbread.
