Slow Cooker Italian Stuffed Peppers

I'm always looking for ways to sneak more nutrition into my main dishes but my kids (even the adult ones can be picky) aren't often receptive. Spinach packs a lot of bang for the buck but it's on the "I don't eat that!" list. I learned long ago that if I grind the offender up into tiny pieces there is no way it could get left on the plate. So that's what I did here. The veggies help to keep the filling moist during the long cooking period.
