This stupidly simple sweet potato tagine gets a big hit of flavour from rose harissa and ticks both the vegan and vegetarian options, and it is just as good as a main course as it is as a side dish.
Top and tail, then peel and cut the onion into 8 wedges and break them into individual "petals".
Peel the sweet potato and cut it into thick rounds about 25mm (1") thick, then cut each of these rounds into 6 or 8 wedges, depending on the thickness of your sweet potato.
Tear the pitted dates into strips.
Combine the vegetable stock with the rose harissa, sumac, dried mint and salt.
Place the onions in the base of the tagine (20-22cm or 8-9"), followed by the wedges of sweet potato and arrange them into a flat layer.
Add the almonds and dates, making sure they are evenly distributed.
Pour over the sauce that we made, followed by the olive oil.
Sprinkle over the zaatar and brown sugar.
Finally, add the tagine lid and makes sure it sits well, then turn the heat to low-medium and cook for 45 minutes or until the sweet potatoes are cooked.
