Prep the fish: Soak the cleaned fish in lime juice for 30 minutes. Rinse and pat dry with paper towels.
Season: Make three slits on each side of the fish. Mix salt and black pepper (a little more pepper than salt) and rub all over, including inside the cavity.
Butter up: Spread a light layer of butter over the fish to help the seasoning stick.
Mix the stuffing: Combine okra, corn, carrot, onion, thyme, and fish soup mix.
Stuff and wrap: Place the seasoned fish on a large piece of foil, stuff the cavity with the vegetable mixture, and spoon any leftovers over the top. Wrap tightly.
Bake: Place in a preheated oven at 375°F (190°C) and bake for 45 minutes to 1 hour, or until the fish flakes easily.
Serve: Unwrap carefully, drizzle with lime juice, and serve warm with your favorite sides.
