Fennel-Coriander Halibut with Mixed Peppers

From the pictures below it should be obvious that the spice coating on the halibut is the key to this very simple dish. 

All you need to do is put 1 teaspoon each of fennel seed and whole coriander into a spice grinder (or mortar and pestle) and grind finely. Add lemon zest and salt and fresh ground pepper. Drizzle with olive oil and roast for about 10 minutes at 425 degrees. 

For the peppers, just sauté sliced peppers and onion, salt, pepper and some cayenne.
