How to cook
Rip the broccoli into florets and boil them in salted water. Let them drain.
Put half of the grated cheese in an oven dish. Cover it with the broccoli and sprinkle with breadcrumbs. Put the onions with nuts on top and cover with the remaining grated cheese.
Bake in a preheated 392°F (200 °C) oven until the cheese melts.
