How to Make It
Preheat broiler with oven rack in top position. Place bell pepper halves on a foil-lined baking sheet, skin sides up; flatten slightly by pressing with heel of hand. Broil until blackened, 8 to 10 minutes. Remove from oven, and wrap in foil used to line pan. Let stand 10 minutes. Rub off and discard skins.
Place pita in a food processor; process until coarsely ground, about 30 seconds. Add bell peppers, oil, pomegranate molasses, Aleppo pepper, cumin, salt, and garlic; process until smooth, stopping to scrape sides as needed. Add walnuts; pulse until almost smooth but with some small chunks, 4 to 5 times.
