Topped with buttery herbed breadcrumbs and melty fontina, these sausage-stuffed cheesy mushrooms will convert even the biggest mushroom-hater. They’re pretty enough to serve with champagne, and thanks to the protein- and calcium-rich cheese, substantial enough to be retooled for dinner — just add your favorite bite-sized pasta.
Note: Feel free to use vegetarian or chicken Italian sausage if you prefer.
