Place the onions and fennel in a baking dish and toss with olive oil. Add the wine and bake at 200 for 30 minutes.
Cook the pasta until al dente and then drain.
Toss the pasta with the fennel mixture, basil, olives, capers and caper berries to garnish
Season to taste, the olives and capers should mean that you do not need to add any salt but only black pepper and dress with the parmesan.
