Tumbet

• 200 ml/7 fl oz/scant 1 cup olive oil
• 8

This is a classic vegetable dish from Mallorca consisting of layers of fried peppers, aubergines (eggplant) and potatoes in a rich tomato sauce. I love to serve it with a few crispy, grilled lamb cutlets straight from the barbecue.

Preheat the oven to 180°C/350°F/gas mark 4.
