Step 1
Bring a large pot of water to a boil and salt it. Put half the oil (2 tablespoons) in a medium skillet over medium heat. When it’s hot, add the bread crumbs and cook, stirring frequently, until golden and fragrant, less than 5 minutes, and then remove. Add the remaining oil and the onion to the pan, sprinkle with salt and pepper, and cook, stirring occasionally, until softened, about 5 minutes.
