  1. Heat oven to 180C/160C fan/gas 4. Peel the aubergine with a potato peeler and roughly spread the miso paste all over it – the best way to do this is with the back of a spoon.

  2. Put it in a roasting tin along with the sweet potato wedges. Pour 225ml boiling water into the base of the tin, then add the oil, ginger and garlic. Sprinkle a pinch of salt over the wedges and place in the oven.

  3. After 30 mins, pour another 125ml boiling water into the base of the tin and roast for another 20 mins. Repeat, adding 50ml boiling water and the spring onions, and roast for 10 mins more. Check the aubergine is cooked by inserting a knife in the centre – if it is ready it will easily slide in and out, and the aubergine will be soft on the inside.

  4. Sprinkle the chopped parsley over the potato wedges, slice the aubergine into 2cm thick ‘steaks’ and serve on top of the potatoes. If there is no sauce in the bottom of the tin, add 3 tbsp water to loosen up the miso, then pour the miso gravy over the aubergine steaks and sprinkle with cracked black pepper.

I haven't tried this recipe so can't rate it but 6g of protein (only just more than a tenth of your daily recommended amount) in what is supposed to be a main meal strikes me as, frankly, irresponsible. It is not a balanced meal at all and I think that this should be made clear. It's a problem I've noticed with many of BBC good foods Vegan recipes, and I find it highly frustrating.

Excellent. My son made this for my birthday dinner. If you have any leftovers, the aubergine is also good, slivered and stir-fried.

We used less liquid and the aubergine was still too soggy. Finishing it off under the grill help crisp up the edges though. Also splashed in some Shaosing rice wine which worked quite well.

Tasted great but the texture was a bit gross, maybe I added the water too quickly or something.

SO tasty! Added a little more water than stated at each stage to stop it drying out; great results!

hello! I like to batch cook meals to draw out over several days, obviously this recipe is really delicious but is lacking in protein and fat, is there anything I can add which will keep it vegetarian but boost its nutritional value?

Thanks for getting in touch. You could try cooking with tofu or adding some toasted seeds. Our vegetarian collections might have some nice ideas http://www.bbcgoodfood.com/recipes/collection/vegetarian. Let us know how you get on.

Can the miso paste be substituted for anything else?

Hi there – thanks for your question. The timings should be fine to roast the aubergine with any flavouring you like – spread with olive oil, your favourite curry paste or marinade - all should be fine to use instead of the miso paste. If you want to achieve a similar flavour use soy sauce and a tiny bit of sesame oil if you have it. Hope this helps, let us know how you get on.

Hi janekinson, thanks for your question, you could try this recipe with 2 or 3 large courgettes or 375g tofu. However, we haven't tested doing so in our kitchen so cannot guarantee perfect results. Let us know how you get on.

Swap the parsley for coriander and mint to add an extra zing!
