Mushrooms and onions finely chop.
Fry in vegetable oil.
Transfer to a deep bowl to cool.
Add minced meat. Salt-about 1 teaspoon.
Take the smallest spoon (I have coffee), if not - the narrowest fork.
Put in a deep frying pan or saucepan.
Position over short distances to avoid bonding.
Pour the cream and close the lid (be sure to have a hole in the lid to remove steam).
If you want the cannelloni turned out drier - fill them halfway or 2/3 of the cream. All cream will be absorbed inside.
If you want that they turned out gentle and juicy - fill completely.
To put on the small fire for 10 minutes, then turn and leave for another 5.
You're done! Before serving sprinkle with grated cheese.
