For the roulade dough, half-defrost the spinach. Just so that it can be mixed with the rest of the ingredients. Preheat the oven to 180 degrees.
Mix the eggs with 100 g of grated cheese and the thawed spinach, spread on a baking sheet lined with baking paper and bake for about 15 minutes. Remove, sprinkle another 100 g of grated cheese on top and put in the oven for another 5 minutes. Take out and let cool.
Spread the cream cheese on the cooled spinach plate, cover with the smoked salmon slices and roll up a little tighter using the baking paper. Refrigerate. Then cut diagonally into slices.
