Ratatouille

Cut the aubergines in half lengthways. Place them on the board, cut side down, slice in half lengthways again and then across into 1.5cm chunks. Cut off the courgettes ends, then across into 1.5cm slices. Peel the peppers from stalk to bottom. Hold upright, cut around the stalk, then cut into 3 pieces. Cut away any membrane, then chop into bite-size chunks.

Score a small cross on the base of each tomato, then put them into a heatproof bowl. Pour boiling water over the tomatoes, leave for 20 secs, then remove. Pour the water away, replace the tomatoes and cover with cold water. Leave to cool, then peel the skin away. Quarter the tomatoes, scrape away the seeds with a spoon, then roughly chop the flesh.
