Preheat the oven to 200ºC/400ºF/gas 6. Soak the farro or bulgar wheat
in cold water for 20 minutes, then drain. Slice the courgettes across
into chunky half-moons and put them into a large roasting tray. Add the
remaining vegetables and the garlic cloves and toss together with a
good splash of olive oil. Season well with salt and pepper. Try to
spread the vegetables out in one layer, as they’ll roast better this
way (use 2 trays if you have to). Roast in the preheated oven for 30 to
40 minutes, removing the trays and carefully shaking them now and then,
until the vegetables are cooked through and crisp around the edges.
Sprinkle a little vinegar over the vegetables as soon as they come out
of the oven and set aside to cool. When cool, tip on to a large
chopping board, add the fresh herbs and chop finely.
Place the farro or bulgar wheat in a large saucepan, cover with fresh
cold water and bring to the boil. Simmer for 20 minutes, or until
tender, and drain well. Dress with olive oil and the lemon juice,
season with salt and pepper, and toss with the roasted herby
vegetables. Scatter over the reserved fennel tops and serve.
