A rabbi recently told me that rav ovadia yosef has a "Mishna Berura" style commentary on the shulchan aruch. (I presume he wasn't referring to his son's work Halacha Berura.) anyone know what this work is if it exists?
The answer to your question is a Sefer called Yalkut Yosef.
I believe they are talking about his sefer Chazon Ovadia.
