Kale. We grew kale for our dog's food (which we have switched to a completely meat, bones, and organ diet) Now we have an endless supply of Kale growing in our garden. Every time we go out to the garden we grab a handful of Kale and toss it into them. It's funny to watch them pick it up and toss it over their heads
And rice noodles, man do they love rice noodles too.
