Place all the ingredients in the cup of a blender. Blitz until you reach the desired consistency - I always stop just before smooth to give it a little texture. Set aside.

Heat a medium frying pan over a medium heat and add the olive oil. Once at temperature, add the chunks of jackfruit chunks. Tossing or stirring frequently, allow the jackfruit to brown lightly.

Once browned, using a fork or a potato masher, break the jackfruit into rough shreds. Add the oregano and salt and keep over the heat - cook for a further 2 minutes then remove from the heat.

Preheat the grill/broiler to full temperature. Arrange the slices of bread on a grill tray. Place under the grill and toast lightly until crisp. Remove the grill tray from the oven and remove one of the slices. Flip the remaining slice of bread and spread with the vegan mayo. Top one side with the cooked jackfruit and then top the jackfruit with the vegan mozzarella. Place under the grill/broiler until the mozzaella is melted and starting to brown. While the cheese is grilling, spread the untoasted side of the other slice of bread liberally with the pesto.

Remove the cheesy jackfruit slice from the oven once grilled and top with some freshly sliced red onion. Top with the pesto covered bread and enjoy.
