How to make
Rip the broccoli into florets and boil them in salted water. Let them drain.
Finely chop the onions and braise them in the olive oil until transparent. Add the crushed hazelnuts and almonds.
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 390°F (200 °C) oven until the cheese melts.
