Roast the nuts and 1 tablespoon of oil in a frying pan, remove. Cut bread into cubes and soak in the cream. Clean broccoli, cut into florets from the stalk and wash. Prepare pasta in boiling salted water according to package instructions.
Add broccoli to the pasta about 5 minutes before the end of the cooking time. Wash oregano, shake dry, pluck leaves from the stalks. Peel garlic. Mash nuts, bread, garlic and oregano in a mortar, except for something to garnish.
Stir in oil and 2-3 tablespoons of pasta water, season with salt and pepper. Drain the pasta and broccoli. Put them back into the pot and fold in the walnut sauce. Arrange noodles on plates, garnish with remaining oregano.
