Preheat your oven to 220°C/200°C fan/gas mark 7. Chop the potatoes into 2cm chunks (no need to peel).

Trim the aubergines, then slice into rounds approximately 1cm thick. Lay them onto a baking tray. Drizzle with oil, season with salt and pepper, then toss to coat. Spread out in a single layer.

When the oven is hot, roast the aubergine on the top shelf until soft and golden, 20-25 mins. Turn halfway through.

Meanwhile, pop the potato chunks 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 middle shelf until golden, 30-40 mins. Turn halfway through.

While everything cooks, peel and grate the garlic (or use a garlic press). Trim the green beans.

Heat a drizzle of oil in a large frying pan on medium-high heat. Once hot, stir in the garlic and cook for 1 min.

Add the chopped tomatoes, veg stock paste, oregano, sugar and water for the sauce (see pantry for both amounts) and stir together. Season with salt and pepper.

Bring to the boil, then reduce the heat and simmer until thickened, 8-10 mins.

Meanwhile, grate the cheese.

Once thickened, spoon a third of the tomato sauce into an appropriately sized ovenproof dish and spread out in an even layer.

Lay a third of the roasted aubergine slices on top, then generously sprinkle with a third of the grated hard Italian style cheese. Repeat this two more times with the remaining sauce, aubergine and cheese - parmigiana made!

Scatter over the Cheddar, then bake on the top shelf of your oven until golden and bubbling, 8-10 mins.

While the parmigiana bakes, wash the tomato sauce pan and pop back on medium-high heat with a drizzle of oil.

Once hot, add the green beans and stir-fry until starting to char, 2-3 mins.

Add a splash of water and immediately cover with a lid or some foil. Cook until the beans are tender, 4-5 mins.

Remove from the heat and season with salt and pepper.

When your parmigiana's ready, allow to stand for a couple of mins before serving.

Share between your plates and serve the mini roasties and green beans alongside.

Enjoy!
