Is there a simple way to insert text into each line of a table of contents?

I have a LaTeX document (memoir class) broken into unnamed, numbered chapters, like so \chapter{}.

I'd like the table of contents to look roughly like this:

Contents

Chapter 1 ............... 1

Chapter 2 ............... 5

However, \tableofcontents generates the following:

Contents

1 ............... 1

2 ............... 5

Is there a way to insert the word 'Chapter' into each line of the table of contents, preferably without naming the chapters and re-configuring the chapter titles?

I've done a fair amount of searching and have looked into tocloft, titletoc and other such packages, however I haven't found a solution to this particular problem.

I'm hoping I've missed something simple here.
