Preheat oven to 180°C.
Drain and rinse the jackfruit, then cut out the hard core. Some people discard the hard core, but we cut it thinly into stripes and use it in the recipe!
Add the jackfruit, bbq sauce and water into a hot skillet and simmer for 20 minutes or until the jackfruit is soft and the sauce has thickened. Then shred the jackfruit by squashing it with the back of a wooden spoon.
Start to layer the nachos in an ovenproof dish or pan. First lay two handfuls of tortilla chips, then half of the jackfruit, cheese, red onion and tomato. Then repeat for a second layer using up the remainder of the tortilla chips, jackfruit, cheese, red onion and tomato.
Bake for 15 minutes in the preheated oven.
Remove the nachos from the oven and top with a handful of jalapeño and coriander (cilantro), and a serving of guacamole and sour cream.
