I mean, I'll happily eat 10 olives as part of a salad, or 20 straight-up as a snack. You've gotta rinse them off first, though. Also, the cheap brands are less oily and salty.
Rinse them? I spear them right out of the jar. I love 'em. I'll try rinsing one today to see what that's like, but I suspect the oil and salt is a big part of why I like them.
