In a large, deep skillet, heat the 1/4 cup of olive oil. Add the broken spaghettini and cook over moderate heat, stirring frequently, until the pasta is golden, about 5 minutes. Transfer the pasta to a plate. Add the sliced chorizo and onion to the skillet and cook over moderately high heat, stirring occasionally, until the chorizo is browned and the onion is softened, about 7 minutes. Return the pasta to the skillet and stir in the chickpeas and sliced roasted peppers. Add the white wine and cook until evaporated, about 2 minutes.
