Crush or finely chop half the garlic*. Peel and finely grate the ginger. Shred the carrot using a julienne peeler or coarsely grate with a box grater. Halve the cucumber lengthwise, then thinly slice on an angle. Finely chop the coriander, keeping the leaves and stems separate. Thinly shred the cabbage with a sharp knife or mandoline.
Step 2 — Marinate prawns
Combine the garlic, ginger, coriander stems, 2 tsp soy sauce and 1 tsp honey in a large bowl. Add the prawns and toss to coat.
Step 3 — Make slaw dressing
Finely grate the zest of half the lime*, then juice the half. Combine the aioli, sambal oelek, lime zest, 2 tsp lime juice and 1 tbs cold water in a bowl, then season with salt and pepper.
Step 4 — Toast coconut
Put the coconut in a cold medium frypan over medium heat. Toast, tossing, for 2-3 mins until evenly golden. Remove from the pan.
Step 5 — Cook prawns
Heat 2 tsp oil in the same pan over high heat. Cook the prawns, stirring, for 2-3 mins until just cooked through. Remove from the pan.
Step 6 — Get ready to serve
Put the carrot, cucumber, coriander leaves, cabbage and half the dressing in a large bowl, season with salt and pepper, then gently toss to combine. Divide the slaw and prawns among plates. Drizzle with the remaining dressing and scatter with the toasted coconut to serve.
