Marinated Summer Vegetables

This vibrant dish of marinated summer vegetables celebrates the natural sweetness of sun-ripened produce. By roasting colourful peppers and tender courgettes at a high heat, you achieve a delicious char that pairs perfectly with a sharp sherry vinegar and garlic dressing. Fresh oregano adds a fragrant, earthy note that ties the savoury flavours together, creating a versatile salad that improves the longer it sits.

As a healthy vegan option, these vegetables are a wonderful addition to a mezze platter or as a side for alfresco lunches. This recipe is an excellent choice for meal preparation, as the flavours develop beautifully over several days in the fridge. Simply serve at room temperature with some crusty bread to soak up the herb-infused olive oil.

How to make Marinated Summer Vegetables

Place racks in upper and lower thirds of oven; preheat to 475°. Place squash and peppers on separate baking sheets. Drizzle each sheet of vegetables with 1/2 tablespoons oil, season with salt and pepper, and toss to coat. Spread out in a single layer, turning peppers skin side up.

Roast peppers on upper rack and squash on lower rack, turning squash once, until tender, 15-20 minutes. Let cool slightly; remove skins from peppers.

Whisk garlic, vinegar, and remaining 3 tablespoons oil in a large bowl; season with salt and pepper. Add vegetables and oregano; toss to coat. Cover and let sit at least 1 hour.

DO AHEAD: Vegetables can be made 3 days ahead. Cover and chill; bring to room temperature before serving.
