Very gentle, summery and delicious! If someone confuses onions for Breakfast, it is better to "eat" on the weekends. Of course you can do from a pita - but for us it is too much :)
Finely chop the onion, lightly suppress it, a little salt, and add a little vinegar - set aside to infuse. Cut the cucumbers and tomatoes squares, there is green onions. Sausage and mozzarella cut into squares.
To the vegetables add the onion, mix well. Add a little sugar, salt, herbs.
Each half (in the sense all 4 pieces) with one hand lightly greased with sour cream, and the top is not zadnica.
On one half spread the sausage, cheese on the other.
Assemble cake: 1 layer of sausage, 2 layer - salad, 3 layer with cheese, cover with a 4th lawasia smeared side down.
Wrap all this happiness in foil and in the fridge for 15 minutes.
