Add the onion and bell peppers. Toss to coat evenly.
Stir in the okra and cook over medium heat until the onion is translucent.
Add the tomatoes, wine, lemon juice, parsley and Cajun seasoning.
Simmer, stirring occasionally, until the tomatoes soften.
Taste and add salt and pepper as needed.
Add the shrimp and continue cooking for 3-4 minutes, or until the shrimp turns pink and opaque.
