Slow cooker ratatouille recipe
 Tender Mediterranean vegetables in a rich tomato and garlic sauce are a cinch to prepare in a slow cooker. Ratatouille will keep well in the fridge for up to three days. Don’t be tempted to skip some of the olive oil here as it adds a real silkiness to the sauce. Serve just warm or at room temperature with fresh basil and lots of crusty bread or as an accompaniment to grilled meats and fish – it even works as a pasta sauce. 6 tbsp extra virgin olive oil1 medium aubergine, cut into roughly 3cm/1¼in chunks2 medium red onions, thinly sliced4 garlic cloves, very thinly sliced2 medium courgettes, halved lengthways and cut into roughly 2cm/¾in slices1 large red pepper, cut into roughly 3cm/1¼in chunks1 large yellow pepper, cut into roughly 3cm/1¼in chunks400g tin chopped tomatoes2 tbsp tomato purée2 tsp caster sugar1 tsp dried oregano2 dried bay leaves, or 1 fresh bay leafsalt and freshly ground black pepper 6 tbsp extra virgin olive oil 1 medium aubergine, cut into roughly 3cm/1¼in chunks 2 medium red onions, thinly sliced 4 garlic cloves, very thinly sliced 2 medium courgettes, halved lengthways and cut into roughly 2cm/¾in slices 1 large red pepper, cut into roughly 3cm/1¼in chunks 1 large yellow pepper, cut into roughly 3cm/1¼in chunks 400g tin chopped tomatoes 2 tbsp tomato purée 2 tsp caster sugar 1 tsp dried oregano 2 dried bay leaves, or 1 fresh bay leaf salt and freshly ground black pepper Method Heat 2 tbsp of the oil in a large non-stick frying pan and fry the aubergine for 3–5 minutes over a high heat, or until lightly browned on all sides.
