Heat the oven to 200°C/400°F. Heat a drizzle of oil in a saucepan and add the onion and garlic. Fry until soft then add the jackfruit and fry for another 5 minutes.
Add the spices and season well with salt and pepper. Pour in the tomatoes and stock, turn up the heat and simmer until most of the liquid has evaporated. Stir in 1 tablespoon of BBQ sauce.
Spread the jackfruit out on a baking sheet and put in the oven for 15 minutes. Add the rest of the BBQ sauce and turn the heat up to 225°C/440°F. Cook the jackfruit for another 15 minutes then serve in sandwiches.
