Roast bell peppers on a sheet pan for 20 minutes at 400 degrees by splitting in half and deseeding. Flip once halfway. You can toast your walnuts in the oven at the same time by placing walnuts on a sheet pan and letting roast for about 10 minutes (keep an eye on them so not to let them burn).
Put red peppers and walnuts in blender with other ingredients and blend until smooth and creamy.
Garnish with a drizzle of olive oil, a drizzle of pomegranate molasses and a sprinkle of crushed red or Aleppo pepper.
