Finely dice the bell pepper and crush the garlic. Rinse and drain the jackfruit pieces. Heat the olive oil in a saucepan over a low/medium heat and add the onion, garlic, bell pepper, jackfruit, dried herbs and spices. Stir well and cook gently for 4-5 minutes until tender and fragrant.
Add the tomato purée and stock. Stir well and bring to a gentle boil. Reduce to a simmer for 10 minutes until all the liquid has been absorbed.
Whilst the jackfruit is cooking, slice the zucchini in half and cut off the very top and bottom and discard. Use a spoon to carefully scoop out a channel in the center of each zucchini half.
Heat a griddle pan over a high heat and add the zucchini cut side down. Cook for 3-4 minutes each side until tender and charred.
Shred the jackfruit using two forks and divide between the two zucchini halves to serve.
