Steps
1. In a bowl, mix the Gochujang with a pinch of salt and pepper. Marinate the kangaroo steak in this mixture for at least 30 minutes.
2. While the steak marinates, prepare the pickled vegetables. In a small bowl, combine vinegar, sugar, lemon myrtle, and a pinch of salt. Add the carrot, cucumber, and radish, and let them pickle for at least 15 minutes.
3. Heat a skillet over medium-high heat and add a little oil. Cook the marinated kangaroo steak for about 3-4 minutes on each side for medium-rare, or until cooked to your preference.
4. Toast the mini burger bun lightly in the same skillet.
5. Assemble the slider: place the kangaroo steak on the bottom bun, add a layer of quandong chutney, and top with pickled vegetables before placing the top bun.
6. Serve immediately and enjoy your unique Australian mini slider!
