Method

  1. Heat half the oil in a large frying pan over a medium heat and cook the onions for 4-5 mins, stirring, until softened. Reduce the heat to low and add the garlic; cook for 1 min. 
  2. Add the remaining oil to the pan and fry the aubergines over a medium heat for 4-5 mins, stirring, until starting to brown. 
  3. Transfer to a large slow-cooker (at least 5.5ltr capacity) along with the cooked onions, the courgettes, peppers, passata, tinned tomatoes, sugar, dried herbs, vinegar and half the parsley. Season, mix well, then cook on high for 3-4 hrs (or on low for 5-6 hrs), stirring occasionally, until the veg is soft and the sauce has thickened. Scatter over the remaining parsley and serve with crusty bread, if you like.
 

Cook's tip: No slowcooker? Put everything in a casserole dish, cover with a lid or a double layer of foil and cook in the oven at gas 2, 150°C, fan 130°C for 1 hr 30 mins, stirring halfway.
