Preheat the oven to 200C. Wash and dry the potatoes, prick the flesh with a fork and bake for 25 mins on a baking tray.
Meanwhile, wash the spinach well, removing tough stems and ro ots if attached. Wilt in a large pan over medium heat for 4 mins. Remove from the pan, squeeze dry and chop on a chopping board with the broccoli, cloves of garlic and thyme leaves.
Remove the potatoes from the oven when done. Peel and cube, place the flesh in the tian, casserole or 20cm Pyrex dish. Drizzle the with olive oil and return to the oven.
In a medium bowl beat the eggs well, add the grated cheese and pine nuts, season and add the spinach mixture.
Remove the hot potatoes from the oven and pour the spinach mixture over, mix well and return to the oven for 20 mins. The finished dish should have a golden brown fluffy crust and a most enticing smell.
Enjoy with a good hunk of bread to mop up any juices.
