Preheat the oven to 200C, fan-forced. Line an oven tray with baking paper. Cut the unpeeled sweet potatoes into 1.5cm-thick chips. Put the chips on the lined tray, drizzle with 2 tsp olive oil, season with salt and pepper and toss to coat. Roast for 25 mins or until golden and tender.
Step 2 — Prep slaw ingredients
Meanwhile, shred the cabbage with a sharp knife or mandoline. Shred the carrot using a julienne peeler or cut into thin matchsticks. Pick the parsley leaves, discarding the stems.
Step 3 — Prep coating ingredients
Whisk 1 egg in a bowl. Combine 1 tbs flour and a pinch of salt in a shallow dish. Combine the breadcrumbs and dukkah in a separate shallow dish.
Step 4 — Crumb chicken
Put the chicken flat on a board, put your hand on top and halve horizontally into fillets. Dust the chicken with the flour, shake off the excess, then dip in the egg and coat in the breadcrumb mixture.
Step 5 — Cook schnitzels
Heat 1cm oil in a medium frypan over medium heat. Cook the chicken schnitzels for 2-3 mins each side until golden and cooked through. Drain on a wire rack set over paper towel (this will keep the crumb crisp). Season with salt.
Step 6 — Toss slaw and serve
Thinly slice the apple, discarding the core. Put the apple, cabbage, carrot, most of the parsley and half the horseradish dressing in a large bowl, then toss to combine. Divide the slaw, schnitzels and chips among plates. Drizzle with the remaining horseradish dressing and scatter with remaining parsley to serve.
