Using RPL to replace spaces with hyphens

I'm trying to see if there's a way to use RPL to insert hyphens where there's a space.

Basically, we're pulling data from our Supplemental Table where some of the text fields will read as normal text. For example, if our column is named "Breakfast", within that column we can have cells that say "Bacon" or "Bacon Eggs Toast".  What I'd like to do is extract that data from that column that says if there's a space within those text fields, insert a hyphen.

So I'll pull "Bacon Eggs Toast" and if there's a way, I can instead display "Bacon-Eggs-Toast"
