Preheat the oven to 375 degrees F.
For the Roasted Onions: Toss the onions in olive oil and season with salt and pepper to taste. Transfer onions to a medium-roasting pan and roast until lightly golden brown and just cooked through about 25 to 30 minutes.
For the Roasted zucchini: Toss the zucchini with the olive oil and season with salt and pepper, to taste. Place in a medium-roasting pan and roast until lightly golden brown and just cooked through, about 20 to 25 minutes.
Place both the zucchini and onions on a large serving platter and drizzle with some of the romeso sauce and chopped parsley. Serve with Spanish Antipasto.
Heat the olive oil in a large saute pan over high heat until smoking. Separately saute the garlic, bell pepper, tomatoes, chilies and bread cubes until lightly browned, about 2 minutes each. Remove each ingredient with a slotted spoon as it's done. Deglaze the pan with the vinegar and red wine.
Place all the Sauteed ingredients and the deglazing liquid into a food processor and blend until smooth. Add the hazelnuts and process until finely chopped. Add the honey and season, to taste, with salt and pepper.
Arrange all ingredients on a platter and drizzle with olive oil. Serve sliced crusty bread on side.
