Preheat your oven to 220°C/200°C fan/gas mark 7.

Bring a large saucepan of water with 1/2 tsp salt on to boil for the potatoes.

Chop the potatoes into 2cm chunks (peel first if you prefer). Halve any thick broccoli stems lengthways.

Halve, peel and thinly slice the shallot. Peel and grate the garlic (or use a garlic press).

When your pan of water is boiling, add the potato chunks and cook until you can easily slip a knife through, 15-20 mins.

Meanwhile, pop the broccoli onto a baking tray. Drizzle with oil, season with salt and pepper, then toss to coat. Set aside for now.

If you'd prefer to, boil your broccoli with the potatoes for the last 3-5 mins of boiling time until tender, 3-5 mins. Remove from the potatoes before mashing. Season with salt and pepper.

Meanwhile, pop the breadcrumbs, lemon & herb seasoning and olive oil for the crumb (see pantry for amount) into a small bowl and mix together.

Lay the basa onto a lined baking tray.

Spoon the herb crumb evenly over the fish, pressing it down with the back of the spoon.

Pop the basa on the top shelf and the broccoli on the middle shelf of your oven to cook until the veg is tender and the fish is cooked through, 12-15 mins. IMPORTANT: Wash your hands and equipment after handling raw fish. It's cooked when opaque in the middle.

Meanwhile, heat a drizzle of oil in a medium frying pan on medium heat.

Once hot, add the shallot and stir-fry until softened, 3-4 mins. Stir in the garlic and cook for 1 min more.

Add the cider vinegar and allow it to evaporate, 1-2 mins.

Pour in the water for the sauce (see pantry for amount) and veg stock paste, then bring to the boil and simmer until reduced by half, 2-3 mins. Vigorously stir in the butter for the sauce (see pantry for amount) until melted, then take off the heat.

Once the potatoes are cooked, drain in a colander and return to the pan, off the heat. Add a knob of butter and a splash of milk (if you have any) and mash until smooth. Season to taste with salt and pepper.

Serve the herb crusted basa with the mash and roasted broccoli alongside, then spoon over the buttery sauce to finish.

Enjoy!
