Wash the fennel, cut lengthways, remove the stalk and cut lengthways into thin strips. Peel and finely chop the garlic. Put the fennel, garlic, cumin, olive oil in a bowl, season with salt and pepper and mix everything well.
Spread the mixture on a coated baking sheet and cook in an oven preheated to 200 ° C (fan oven 180 ° C) for 20 minutes. Add the olives, tomatoes and diced feta 5 minutes before the end of the cooking time.
Serve sprinkled with the fennel greens and serve with baguette or ciabatta with herb butter.
If you don`t want the whole thing vegetarian, the fennel goes great with fried fish fillet.
