Peel and shred all vegetables except garlic and mushrooms (I used a food processor but it can also be done manually).
Chop garlic and mushrooms finely and brown in a little olive oil. Add the spices.
Add all shredded vegetables to the garlic and mushroom mix. Cover with a lid and let the vegetables cook in their own juices for about 15min stirring occasionally. Season to taste.
Cook the bulgur according to instructions. Rinse under cold water to stop it from further cooking.
Open the feta cheese and crumble it with your hands.
When soft but still firm, place the vegetable mix onto an oven-proof casserole dish. Top it up with the feta and cooked bulgur.
Bake at 200 degrees until the bulgur crust is golden brown.
