Well wash the cauliflower. Entirely boil it. I cooked on steam in a steamer. By the time I turned about 25 minutes. Can be boiled in a pot (as usual) or in a pressure cooker (3 minutes on position 1). In General, as someone comfortable.

The spinach I had frozen. First, I thawed it, then finely sliced.

To make the sauce "Bechamel". This time I did it according to the recipe, not butter, and olive oil. Flour fry until Golden brown, slowly add the milk and continuously stir, to not have lumps. But, as I have said in other recipes, if there are lumps, don't worry, armed with a blender and smash them into smithereens :). The sauce to cook until thick. The finished sauce aside.

Spinach can also be boiled until tender (it cooks very quickly). And you can, I, bring to readiness in the pan for 5 minutes.

The spinach is ready add in the prepared sauce "Bechamel". Mix well. Season with salt and pepper, add the nutmeg and cook on heat for 2-3 minutes.

Boiled cauliflower disassemble on inflorescences, put in a heatproof dish, pour the prepared sauce. Then sprinkle with cheese and bake in the oven or on the grill for 5 minutes. Cheese needs to be baked. I baked it in the oven at 200 degrees for 5-10 minutes.

Serve hot. Bon appetit!
