For this sandwich I made homemade salted cucumbers. Used only honey and soy sauce. Cucumbers cut into thin slices, pour 2 tbsp of soy sauce and boiling water, add the honey, stir (you can add a few sprigs of herbs to taste, I added a bit of thyme and dill) and put into the fridge for a day.

Now, just before cooking the sandwich cake we need to cook the mushroom layer. For the mushrooms and the leek cut into thin slices/rings and evaporate in the pan with the thyme and 1 tbsp soy sauce Kikkoman Sukiyaki. In principle, this can also be done in advance.

Prepare the bread. We need to trim the upper and lower crust over the cut loaf into 3 parts, the middle part to fry on the grill from two sides, the top and bottom one. I used the electric grill, use a grill pan, or toast the bread on a dry pan. Then roasted side a little grease with butter. Roasting and use of butter allows our cakes to not fall apart in the cake.

Collect the cake: on the bottom part of the bread, stack the mushrooms (here I made a blunder, it is better to put the mushrooms under a layer of salad), then lettuce, cheese, intermediate bread (which is fried on both sides). Followed by homemade salted cucumbers, ham, cheese and the upper bread. In General is beautiful)) And delicious. Directly in this stick cake sandwich in the oven degrees to 200-220, and you can go on)

Namely, gently press the cake and trim to a rectangle (or square).

The fry cake on an electric grill or pan-grill (then alternately from both sides, gently turning and pressing while cooking). Electric grill is quite heavy, so I got the cake slightly decreased in height. That gave me the idea that you can add at least another couple of layers...)

You can then stack a cake-a sandwich on lettuce leaves, garnish with tomato and sour cream and serve.

And you can put a couple of slices of cheese, roast under the grill in the oven, then garnish with lettuce, tomatoes and sour cream. So it looks more like a cake.
