How to open a file in a list of files in Vim?

I have a longish list of files opened in vim that looks like this:

/dir1/file1
/dir2/file2
/dir2/file3
.....

How can I open all of them one by one the easiest way possible in the same session of vim either with split or edit?

I'd say with -p for tabs

vim -p `cat yourlistoffiles`
