Make the slaw. Finely slice 60 g red cabbage, 20 g kale, 1 medium carrot, and 20 g white onion with a mandoline (or knife for the kale) and add to a large bowl. Next, add 1 tablespoon olive oil, ½ teaspoon apple cider vinegar, salt and pepper, and 3 cloves garlic. Massage the dressing into the vegetables and set aside.
Slice 4 vegan burger buns in half and heat gently.
Whip up the burger sauce. In a small bowl, combine 2 tablespoons hot sauce and 3 tablespoons vegan mayonnaise.
Slather the buns with the burger sauce, then add 4 large pieces frisee lettuce. Top with the crispy fried oyster mushrooms, then pile high with slaw and top with the bun.
Notes
* You can make the vegan fried oyster mushrooms in advance of time and reheat them when ready to make the vegan fried chicken burgers.
