Take a large saucepan, spray with 1kal and fry the aubergine in batches until it is nicely browned on all sides (2-3 minutes per batch). Remove from the pan and pop to one side.
Next add the onion, peppers, courgette and cumin to the pan and spray with 1kal. Fry for 3-4 minutes until the onion is soft and then add the aubergine back into the pan.
In a jug mix together the tomato puree, red wine vinegar, harissa paste, honey and vegetable stock. Stir until well combined and then pour into the pan over the veggies. Add a lid and simmer on a medium heat for 10 minutes. Remove the lid and then simmer for a further 5 minutes uncovered (this will reduce the stock down further so the dish is not watery). The lovely flavoured stock should start absorbing nicely into the veggies.
If you are having with cous cous, prepare this according to the packet instructions and let it cook whilst the veggies are simmering.
Remove from the heat and add half the feta, mint and parsley. Squeeze in the juice of ½ a lemon and stir.
To serve add the cous cous to a bowl, top with the stew and finish with a sprinkle of the reserved feta, mint, parsley and lemon juice.
Enjoy!
