Grilled Vegetables

This vibrant grilled Mediterranean vegetable dish is a celebration of seasonal produce, bringing together the smoky flavours of the barbecue with a zingy garlic and herb dressing. By charring the peppers, aubergines, and courgettes over a high heat, you unlock a natural sweetness that pairs perfectly with the acidity of the red wine vinegar. It is a versatile recipe that works equally well as a light lunch or a sophisticated side dish for any summer gathering.

As a naturally vegan option, these vegetables offer a colourful and healthy addition to your outdoor dining repertoire. The secret lies in the preparation, using skewers to keep the red onion wedges intact and steaming the peppers to ensure the skins slip away easily. Serve this warm or at room temperature alongside some crusty bread to soak up every drop of the herb-infused olive oil dressing.

How to make Grilled Vegetables

Prepare grill for direct-heat cooking over hot charcoal (medium-high heat or gas).

Whisk together garlic, vinegar, oil, salt, and pepper in a large bowl, then set aside 2/3 of vinaigrette for brushing.

Halve onion lengthwise and cut halves lengthwise into 1/2"-wide wedges. Thread 1/2" apart onto skewers (to hold layers together). Brush onion and aubergine with some reserved vinaigrette.

Oil grill rack, then grill pepper with onion and aubergine, covered only if using a gas grill, turning occasionally with tongs, until onion and aubergine are very tender, 6-10 minutes; transfer to a large rimmed baking sheet. Continue to grill pepper, turning it until skin is blackened, 1-2 minutes longer. Put pepper in a deep bowl and cover with a plate, then let stand while grilling remaining vegetables.

Quarter courgette lengthwise; brush them and tomatoes with reserved vinaigrette. Grill, covered only if using a gas grill, turning tomatoes less frequently than courgette, until tomatoes are just blistered, about 3 minutes; transfer to baking sheet. Continue to grill courgette, turning, until just tender, 1-3 minutes longer.

Peel pepper and thinly slice flesh. Cut tomatoes into wedges and chop remaining vegetables. Add to bowl of vinaigrette along with herbs and salt to taste, tossing to coat.
