Pickle the cabbage: Add the red wine vinegar, boiling water, salt, and sugar to a mixing bowl. Add in the shredded red cabbage and give it a good mix. Let it sit for 10 minutes.
Jackfruit: Thoroughly rinse the jackfruit under cold water and break up the pieces with your fingers until finely shredded. Press out excess water with your hands.
Marinade: Add the olive oil, smoked paprika, garlic powder, and salt to a medium bowl. Add in the jackfruit and marinate for 10 minutes.
Buns: Preheat the oven to 400°F (200°C) for the burger buns. Bake for 5-7 minutes until golden.
Sauté: Sauté the jackfruit over medium heat with a little olive oil for 10-12 minutes until it turns golden and starts to crisp up.
Serve: Top each bun with a lettuce leaf, a few tablespoons of filling, and some quick pickled red cabbage.
Notes
Jackfruit: just young jackfruit, water, salt, and eventually lemon juice.
