Grilled Mushroom Antipasto Salad

This grilled mushroom antipasto salad is a sophisticated vegetarian dish that brings deep, earthy flavours to the table. By charring a mix of mushrooms over a high heat, you create a smoky base that pairs beautifully with a bright, punchy vinaigrette. The addition of salty Castelvetrano olives and sweet peppadew peppers provides a wonderful contrast, making this a standout course for any Mediterranean-inspired gathering.

Ideal as a light lunch or a versatile side dish for a summer barbecue, this recipe relies on simple, high-quality ingredients. The warmth from the mushrooms slightly melts the shaved Parmesan, creating a rich texture that feels indulgent yet remains healthy. Serve it alongside crusty sourdough bread to soak up the herb-infused dressing and enjoy a restaurant-quality starter at home.
