Heat up the olive oil in a frying pan on medium heat.
Unpack the jackfruit and chop any large bits. Don’t worry about making them too small, they slowly fall apart while cooking.
Fry the jackfruit for about two minutes, stirring occasionally.
If you prefer fried onion to raw onion as relish, then throw it in with the jackfruit now.
Add half of the BBQ sauce and fry for another three minutes.
Thinly slice the onion, gherkins and tomato as relish.
Chop the lettuce.
Give the burger buns a quick toast under the grill or in a toaster. They won’t need long so don’t let them burn!
To serve: 1 tbsp BBQ on the bottom of one bun. Layer over some lettuce, then ½ of the fried jackfruit. Next come the raw onion, gherkin and tomato. Add another dollop of sauce on the top half of the bun – and pop it on top. Done!
