Ingredients

  • 2 whole red bell peppers
  • ½ cup almonds
  • ¼ cup breadcrumbs
  • 3 whole garlic cloves
  • ½ cup olive oil
  • 2 tbsp red wine vinegar
  • 4 whole onions
  • 1 tsp salt

Instructions

  1. 1

    Roast the 2 red bell peppers under a broiler or over a flame until skins are blackened, about 10 minutes. Place in a bowl, cover with plastic wrap, and let steam for 10 minutes.

  2. 2

    Peel the peppers, remove seeds, and place the flesh in a blender. Add 0.5 cup almonds, 0.25 cup breadcrumbs, 3 garlic cloves, 2 tbsp red wine vinegar, and 0.5 tsp salt.

  3. 3

    Blend while drizzling in 0.25 cup olive oil until smooth. Taste and add more salt if needed. Set aside.

  4. 4

    Peel and slice the 4 onions into 1-inch thick rounds. Brush both sides with the remaining 0.25 cup olive oil and sprinkle with the remaining 0.5 tsp salt.

  5. 5

    Grill the onion slices over medium-high heat until charred and tender, about 4-5 minutes per side. They should be soft and have nice grill marks.

  6. 6

    Serve the grilled onions on a platter with the romesco sauce spooned over the top. Enjoy warm or at room temperature.
