Herbivores vs Omnivores

It's finally happened.
Jason and I have seen it coming for several years.
I'm actually a bit surprised it took this long.
Tempe has made the connection that "chicken" on her plate at dinner is the same as "chicken" in our neighbor's backyard chicken coop, or at the farm up the street, or wandering around the zoo.
Tonight at dinner she weepingly asked Dad how he would feel if he died and someone peeled off his skin and ate him.
Then she took a bite of chicken and liked it so much that she ate her whole plate.
That's a moral dilemma right there.
So any tips on a omnivore raising a herbivore?
