And so, it all products that will be needed to prepare this sandwich: bread, mustard and soy sauce (I TM Kikkoman), two kinds of cheese, fresh spinach and onions.

Coat our bread soy sauce and mustard. I use Dijon, but you can take French, and some yadrena))

Now put one piece of bread with half of cheese mixture with onion, top with mozzarella (if you have it shredded, just mix with other cheese and onion), then the spinach, pour a little soy sauce on it, again cheese with onions.

And cover with the second bread. Now sandwiches can be wrapped with foil or plastic wrap and take on the outdoors, where fry both sides on the grill (on the grill) or on the grill. Well, at home fry the sandwiches in the pan and grill, pressing lid. If desired, brush outside of bread with olive oil.
