I recently started to crate my app to create daily menus for restaurants.
My idea was to provide widget with daily menus on facebook page and same for restaurant website.

I know that is possilbe to share facebook widget on your site, but what if you want share your widget on facebook?

I didn´t find any tutorials or article if it is possible.
Do you think it is possible or my idea?
Let me know if you have any experience in this.
