Instructions

  1. Step 1: Preheat the grill to medium-high heat (about 400°F). Place 3 large red bell peppers directly on the grill grates, turning every 5 minutes until skins are blackened and blistered, about 15 minutes total. Transfer peppers to a bowl and cover with plastic wrap to steam for 10 minutes.
  2. Step 2: Meanwhile, place 2 medium sliced zucchinis, 1 medium sliced eggplant (1/2-inch rounds), and 1 large red onion cut into wedges on the grill. Grill vegetables for 4-5 minutes per side until tender with grill marks. Remove and set aside.
  3. Step 3: Peel skins off the steamed roasted peppers and remove seeds. In a food processor, combine peeled roasted peppers, 1/2 cup toasted almonds, 3 roasted garlic cloves, 1 medium roasted tomato, 1 tsp smoked paprika, and 2 tbsp sherry vinegar. Pulse to blend.
  4. Step 4: With the processor running, slowly stream in 1/2 cup extra virgin olive oil until the sauce reaches a smooth yet slightly coarse texture. Season with salt and black pepper to taste.
  5. Step 5: Serve the grilled vegetables alongside a bowl of Romesco sauce for dipping or drizzling.
