Preheat oven to 200°C/400°F. Slice the courgettes and toss with olive oil. Roast on a baking sheet for 25 minutes, until browned and tender. Let cool.
To the food processor, add all the ingredients and blend again until incorporated. Taste and season with salt and pepper.
Transfer to a serving bowl. I like to top with sliced fried courgettes, a drizzle of olive oil and fresh herbs. Serve with your favourite crackers.
