Toasted Bread Crumb Topping
4 slices white sandwich bread, quartered
2 tablespoons unsalted butter, melted
2 tablespoons minced fresh parsley leaves
salt and ground black pepper
Adjust an oven rack to the middle position and heat the oven to 300 degrees. Pulse the bread and butter in a food processor to course crumbs, about 6 pushes. Spread the crumbs out over a rimmed baking sheet. Bake, stirring occasionally, until golden and dry, 20 to 30 minutes. Let the crumbs cool, then toss with the parsley; season with salt and pepper to taste.
