This vibrant grilled panzanella salad is a delightful vegan twist on the classic Tuscan bread salad, celebrating the very best of seasonal summer produce. By lightly charring the peppers, squash, and red onion on the barbecue, you add a wonderful smoky depth that beautifully complements the sweet, ripened tomatoes and salty punch of the capers. It is a fantastic way to use up slightly firm ciabatta, as the bread soaks up the zesty lemon dressing and tomato juices while retaining a satisfying crunch.
Ideal for outdoor dining or as a hearty main course, this plant-based dish is as nutritious as it is colourful. The combination of fresh Italian parsley and aromatic herbs like tarragon and dill provides a sophisticated finish that elevates the savoury notes of the grilled vegetables. Serve this salad at your next garden gathering alongside other Mediterranean-inspired plates for a truly effortless and healthy homemade feast.
