Bring a large pan of salted water to the boil. Place the peas, asparagus and sugar-snap peas in the pan and simmer for 3 minutes. Drain, then refresh under cold running water.
Transfer the vegetables to a large bowl with the courgette ribbons and fennel and mix together.
For the dressing, whisk together the lemon rind and juice, mustard, honey, parsley and half the oil in a separate bowl. Toss the vegetables in the dressing.
Preheat the grill to a hot setting.
For the garlic bread, rub the cut sides of the rolls with the garlic clove, drizzle over the remaining oil, then place the rolls on a baking sheet under the grill and toast on both sides.
Divide the salad between four plates, place the garlic bread alongside and serve.
