Preheat the oven to 220C, fan-forced. Line an oven tray with baking paper. Halve the unpeeled sweet potatoes lengthwise. Put the sweet potatoes, cut-side down, on the lined tray. Drizzle with 2 tsp oil and season with salt and pepper. Roast for 25 mins or until tender when pierced with a fork.
Step 2 — Prep ingredients
While the sweet potatoes are roasting, very thinly slice the cabbage with a sharp knife or mandoline. Thinly slice the cucumber. Thinly slice the spring onion, keeping the white and green parts separate. Pick the coriander leaves, discarding the stems. Coarsely grate the cheese.
Step 3 — Make sesame dressing
Put the sesame oil, 2 tsp soy sauce, 2 tsp white vinegar and ½ tsp honey in a large bowl, season with pepper and whisk to dissolve the honey.
Step 4 — Make cream cheese filling
Scoop some of the flesh from the sweet potatoes, leaving a 5mm-thick shell. Put the sweet potato flesh, white part of the spring onion, grated cheese, cream cheese and 1 tbs chilli paste* in a bowl. Season well with salt and pepper and stir to combine.
Step 5 — Roast filled potatoes
Fill the sweet potato skins with the cream cheese filling. Spray with olive oil (or drizzle with 1 tsp oil). Roast for 10 mins or until golden and beginning to char in places.
Step 6 — Get ready to serve
Meanwhile, add the cabbage, cucumber, coriander, sesame seeds and remaining spring onion to the sesame dressing and toss to combine. Divide the sweet potatoes and sesame salad among plates to serve.
