I recently found out that I just wasn't putting enough stuff in my plain yogurt. I now really prefer good plain yogurt (organic greek is my favorite) with lots of good stuff mixed in:
north dallas honey co.
lots of sliced fruit (I sliced up a whole pineapple on Monday; pineapple is awesome in yogurt!), ground flaxseeds, cocoa, walnuts, and/or coconut
yum...now I just need to start making my own yogurt!
