Cooking Steps
Preheat your oven to 220°C/200°C fan/gas mark 7.
Chop the potatoes into 2cm wide wedges (no need to peel).
Pop the wedges onto a large baking tray. Drizzle with oil, season with salt and pepper, then toss to coat. Spread out in a single layer. TIP: Use two baking trays if necessary.
When the oven is hot, roast on the top shelf until golden, 25-35 mins. Turn halfway through.
Meanwhile, trim and peel the carrot. Use the peeler to peel long ribbons down the length of the carrot, stopping at the core.
Trim the cucumber, then halve lengthways. Chop into roughly 1cm wide, 5cm long batons.
In a large bowl, combine the rice vinegar, half the ginger, garlic & lemongrass puree and the sugar for the pickle (see pantry for amount). Season with salt and pepper.
Add the carrot and cucumber to the bowl and toss through the pickling liquid. Set aside for now.
In a small bowl, combine the sambal and mayo (see pantry for amount). Set aside.
Thinly slice the portobello mushrooms.
When the wedges have 10 mins remaining, heat a drizzle of oil in a large frying pan on high heat.
Add the mushrooms to the pan and season with salt and pepper. Cook, stirring, until golden, 5-7 mins.
Once golden, add the remaining ginger, garlic & lemongrass puree to the pan. Stir-fry for 30 secs, then pour in the soy sauce and fry until there's no liquid remaining, 1 min.
When the mushrooms are cooked, drizzle over the honey (see pantry for amount).
Halve the ciabatta. Toast the ciabatta in your toaster until golden.
If you're using the oven, pop them into the oven to warm through, 2-3 mins.
Just before everything's ready, toss the rocket through the carrot and cucumber pickle.
When everything's ready, spread the sambal mayo over the cut sides of the ciabatta.
Top the bases with a handful of the pickled carrot and cucumber and the honey-soy mushrooms, then sandwich shut with the ciabatta lids.
Serve any remaining pickled veg and the wedges alongside.

Review summary
Updated on Aug 2026- Flavour: The honey-soy mushrooms and pickled vegetables were widely praised for their bold, fresh flavours, making this feel like a satisfying treat.
- Ease of prep: Straightforward to put together, though some found the overall process took a little longer than expected.
- Suggestions: The sandwich can get quite messy and soggy; consider keeping the mushrooms whole or thicker-sliced to help contain the filling, and use a lighter or crustier bread if ciabatta feels too stodgy.
- Next-day meals: Portion size divides opinion — some found it generous, while others suggest adding a protein-rich ingredient such as smoked tofu or halloumi to make it more substantial.
