1 Wash the broccoli and divide into florets. Blanch in boiling, salted water for 5 minutes, then drain and refresh in ice-cold water. Cook the pasta according to the package instructions until al dente. Cut the meat into bite-sized pieces and season lightly with salt and pepper. Crumble the bread rolls and mix with the cheese.
2 Heat the butter and sweat the diced onion until translucent. Stir in the flour and cook briefly without browning. Then gradually add sufficient liquid to produce a thick, lump-free paste. Stir the rest of the liquid in all at once. Bring the sauce to the boil, season to taste and stir in the grated Parmesan.
3 Fill a baking dish with alternate layers of pasta, meat and broccoli. Pour the sauce over and cover with a layer of mixed breadcrumbs and cheese. Dot with butter and bake in a preheated oven (200°C) for about 30 minutes, until golden brown.
