Step One
Preheat the oven to 200°C.
Step Two
Boil the potatoes until tender, then mash them with the salt, eggs and grated cheese. The mixture should be soft but not too runny. Set aside.
Step Three
Wash the spinach well, drain it and chop it coarsely. Soften it either by letting it sit in very hot water for 5 to 10 minutes or by sautéing it in olive oil.
Step Four
Soak the bread in water for 5 minutes, then squeeze it well.
Step Five
In a large bowl, combine the bread with the spinach, milk, salt and cheese. Beat the eggs separately and add them to the mixture.
Step Six
Heat the olive oil in a 28 cm baking pan or ovenproof skillet and spread the spinach mixture evenly inside.
Step Seven
Place tablespoon-sized amounts of the potato mixture over the top of the spinach mixture.
Step Eight
Bake for about 40 minutes, until set and golden.
Step Nine
Serve warm.
Note: If tulum is unavailable, pecorino Romano can be used instead. Kashkaval is also known in Turkey as kaşar.
