This year (and next) in Israel, Shabbat immediately follows the last day of Pesach. Of course, the chametz that people sold has not been bought back, but, as it is no longer Pesach, one can eat chametz.
If one wanted to eat chametz on that Shabbat, can one pre-arrange for the Gentile to whom the Jew's chametz had been sold to come to his home, take his chametz (it now belongs to the Gentile) eat lunch at the Jew's home and just share some of that chametz with the Jew?
There are obviously no chametz issues. However, are there any other issues that I may have overlooked such as benefiting from the Gentile's work; Amira Lenachri or something else?
