Prepare minced meat. Mix semolina with milk and leave to swell for 10-15 minutes. Beef and onion will pass through a meat grinder. Add milk with semolina, egg, salt, pepper and mix the minced meat well.
For the filling, boil hard-boiled 3 eggs, cool and finely chop. Pickled cucumber (you can also pickle, if desired) cut into 6 slices. Wash the corn and mix it with the egg.
On a cellophane bag, form a rectangle from 1/6 of the minced meat.
From the edge, put 2 tablespoons of filling, put a slice of cucumber on top.
Lifting the edge of the bag carefully form a roll. The tips are rounded off with fingers dipped in water. Put our rolls on a baking sheet. Put in the oven (200 degrees) for 40 minutes (until Golden brown).
And we have mashed potatoes as a side dish. While the potatoes are cooking, grate the carrots on a small grater, and finely cut the dill.
Cook the potatoes until tender. You need to make sure that all the liquid does not evaporate. Now we add the carrots, dill, salt, pepper and leave to languish under the lid for 5 minutes. then add the milk, and as soon as it is going to boil, remove the pan from the heat and make a puree. The puree density can be controlled using hot milk ( depending on the friability of the potatoes and your taste)
On a serving plate, spread the roll and garnish, decorate with ketchup.
