Heat ½ cup extra virgin olive oil in the same large skillet over medium heat. Stir in the onion, red bell pepper, garlic, parsley, tomato, oregano, Aleppo pepper, and sugar. Season with salt and pepper. Add ¼ cup cold water and stir well. Lower heat to low, cover the skillet, and simmer for about 12 minutes. Stir occasionally. When done, the onions should be softened but not browned. Leave off heat without cover to cool.
