Potatoes, wash, cut into slices the thickness of 1-1,5 cm, pour salted boiling water and boil until (almost) ready. I boiled the potatoes in Mikrowelle: 10 minutes at a power of 750 Wt

Fish fillets thawed, drain the liquid, the fish rubbed with salt, pepper and lemon juice. Frozen spinach just thawed. Fresh spinach minced, pour salted boiling water for 3 minutes, then drain the water.

For the sauce, mix the egg with sour cream and water, salt-pepper, add grated cheese, mix well.

Almost ready potatoes spread in the form at the bottom of which is poured vegetable oil. Potatoes spread half of the cheese sauce, then distribute spinach, it puts the fish...

...pour the fish remains of the cheese sauce. By this time the convection oven already heated to 220*C, place the form in the bowl of the convection oven low grill. Bake 10 minutes at 200*C, then switch the temperature to 125*C and bake for another 20 minutes. (The fan speed does not indicate I have one - high) After you turn off the grills do not remove the dish immediately, let stand 10 minutes.

And then...

...lay everything on the plates and pour the resulting sauce. Bon appetit! Cold is also delicious!
