Help generating a csv file of users group membership with PowerShell

Hello Powershell Experts,

I'm trying to recreate my work domain on a virtual machine on my laptop to do some testing on.  I have recreated the OU structure.  I have recreated all of the groups (and they are in the proper OUs).  I have recreated all of the user accounts (and they are in the proper OUs).  I have used Powershell and CSV files to do all of the work up this point.  Now I would like to recreate group membership using Poweshell.  My thought was to do something like this in the production domain:

$Users = Get-QADUser  | select samaccountname

foreach ($User in $Users){Get-QADGroup -ContainsMember $user.SamAccountName | select `
    @{n="SamAccountName";e="$User.samaccountname"},
    @{n="Group";e="$_.samaccountname"}
    }

I was anticipating an output like:
SamAccountName                                                                   Group
NickD                                                                                           Domain Users
NickD                                                                                          Accounting
JimJ                                                                                              Domain Users
JimJ                                                                                              IT
JimJ                                                                                             Local Admins
DrewB                                                                                        Domain Users
DrewB                                                                                        HR
DrewB                                                                                        Benefit Admin
DrewB                                                                                        Payroll

I could then take this output and export it to a csv file to move to the test domains and add membership from this file.

The problem is my code doesn't generate any output.  I just get:
SamAccountName                                                               Group





If I run the following, I get an accurate list of groups for the $user.samaccountname:
get-qadgroup -containsmember $user.samaccountname

Please help me out with what I'm doing wrong on this.

Thanks,
Nick
