Ssh sudo pipe command

this command works

ssh -t www.foo.com 'sudo ls -l'

I immediately receive a request for my password, after entering I get the contents of the directory

If I try to execute this command, it will not work - I never ask for a password, so I never get any content.

ssh -t www.foo.com 'sudo ls -l' | grep 'foo'

This is a basic example, I know that I can pass / grep the output in my "ls" command. for my application, I need to pass the output through a program on my host.
