I made
this Lentil Feta salad just now, and left out the onions because I am lazy and don't really like raw onions all that much anyhow. It's fine. (Edit: and the parsley, apprently, because I am forgetful and my parsley was stuff I had in the freezer anyhow.)
Cow's milk feta (Whole Foods' house brand), however, is weird. I'm not a big fan of feta in general, but now I have the remnants of a 1-lb block of it. I wish it were tomato season, at least. Hmm.
