Very easy to make: I simplified it and it turned out great - instructions below:
A quicker way to make is to drain the jackfruit and then chop and mash before frying it in a pan with a chopped onion and olive oil (adding splashes of water if needed).
Then I added all the other ingredients, replacing the sugar with stevia. I didn't have orange juice so I just missed that out. I let it simmer for a few mins - and it was done! This was delicious. Next time I would throw in a can of red kidney or black beans for protein.
