# [Zsh][1], 59 bytes

[try it online!][2]

```lang-zsh
b=${(j::)${(os::)2:l}// };<<<${${(j::)${(os::)1:l}// }:/$b}
```

Similar to [my other anagram solution][3], again using Zsh's gnarly [parameter expansion][4]. Added a few bits to lowercase everything and parse out spaces. Tried to jam everything into one fancy expression but Zsh kept complaining, so I separated out `$b` to make it work.
