Cook until shrimp are half done. Add green pepper, drained tomatoes, green onions and lemon slice. Continue cooking over medium to low heat until shrimp are tender and vegetables are still tender crisp, (If sauce is too think, thin with sauce from drained tomatoes). Check seasonings. Remove bay leaf and lemon slice. Stir in finely chopped parsley. Serve inside of rice ring or over cooked rice.
