Place a 10-inch cast-iron skillet over medium heat and add just enough oil to coat the bottom.
Add okra and cook until it begins to brown, stirring occasionally. (If okra starts to stick, add more oil.)
Then add the next 5 ingredients. Season with salt and pepper. Cook 5 minutes.
Next, add herbs and tomato, including seeds and juice, to the skillet. Cook until shrimp is ready, 2 to 3 minutes more.
If desired, add more salt and pepper before serving.
