cilantro? Not only vile it can kill you too.
I am one of those individuals for which cilantro is a gag food. Tastes like bitter grass. Now, finely chopped cilantro in salsa I have no problem with (salsa needs cilantro).
Thankfully, my favorite taqueria keeps their chopped fresh onions and cilantro separate, so adding onions to my tacos there is not a problem. Yum!
