well let me tell you that it was one of the best side dishes (and by far the easiest!) i have ever made! in fact, we're still eating them cold!!!
i used 5 sweet potatoes, about 6 cloves of garlic (i can't help myself!), didn't use the red pepper flakes and used fleur de sel (because i have it). oh! and i also used dried thyme, about 1 T.
DELISH!!!
