The secret to this speedy soup is buying ingredients with lots of built-in flavor, like hummus and jarred piquillo peppers.
In a blender or a food processor, combine the whole piquillos with the hummus and stock and puree until smooth. Transfer the soup to a medium saucepan. Add the rice and chicken, season with salt and pepper and bring to a boil. Ladle the soup into bowls and garnish with the parsley, sliced piquillos, olive oil and hot sauce.
