There is no such recipe yet, but something similar can be achieved in 
real time, without writing it to RecentChanges, with a PageList:

Try in your WikiSandbox:

(:pagelist order=-time group=Main fmt=#rc:)

(:pagelist order=-time group=Main fmt=#rcode:)

(:if false:)
[[#rc]]
* [[{=$FullName}]] . . . {=$LastModified} by {=$LastModifiedBy}: 
{=$LastModifiedSummary}
[[#rcend]]

[[#rccode]]
  [=* [[=]{=$FullName}]] . . . {=$LastModified} by {=$LastModifiedBy}: 
{=$LastModifiedSummary}
[[#rccodeend]]
(:ifend:)

The second template #rccode will print the wiki code because the line is 
preceded with a space and the start-of-link part of the markup is 
escaped with the [=...=] PmWiki escape characters.

To list all pages in all groups, remove the "group=Main" part.

If you must write it to *RecentChanges, you may be able to copy the 
generated code, remove the initial white space on every line, and place 
it in the *RecentChanges page(s).
