Take a large sauté pan and add a 2-count of olive oil. Add onions and slowly caramelize. When brown and creamy set aside. Heat your grill and wipe down with oiled paper towels to create a non stick surface. Take store-bought flat bread and brush with olive oil. Season with salt and pepper and grill on both sides until warmed through and has nice grill marks.
Transfer to a platter and whilst still warm, smear with mascarpone, sprinkle with crumbled blue cheese, caramelized onions, toasted walnuts and fresh grapes. Season with a few turns of freshly ground black pepper, drizzle with some more extra-virgin olive oil and top with a shower of fresh parsley.
