An adaptation of a recipe I found elsewhere.
For two:

• One large fennel bulb, or two small ones
• Two tomatoes, diced
• A handful of mushrooms in slices, any kind, fresh or dried and soaked
• Two cloves of garlic if you like it as much as we do
• olive oil
• Parmesan cheese
• breadcrumbs
• pepper and salt

Preheat the oven to 200° C (that's pizza temperature, if you're used to Fahrenheit).
Cut the fennel bulbs in four quarters.
Pre-cook them in salted water for five minutes, or put them in the microwave at 800 watts for five minutes.
Grease an oven dish with some olive oil.
Put the fennel in, then the mushrooms, then tomatoes, then garlic (cut up or pressed).
Add some black pepper and salt, then a handful of breadcrumbs, and finish off with a layer of grated parmesan cheese.
Put the dish in the oven for 20 minutes.

Serve over pasta.

We had this just now and it was very nice.
