No but I use greek yogurt to make dips - usually cucumber or caramelized onion.

Cucumber and dill (not dull)

I tried the cucumber and dull and really liked it. It tastes healthy but I like that, and its perfect with some pita chips or on a sandwich.

I tried the veggie/herb I like it!

Never tried it but I usually sub greek yogurt for sour cream and it turns out.

Looks interesting...A lot less fat than sour cream dips.
Are they any good? Which ones have you tried?
