I love plain yogurt and a slice of toast! MMMM! I like when it's a tiny bit tart personally.
Also if you cut up some cucumber and put it in some yogurt, then add a dash or pinch of dill (depending on how much dill you like- it's better with the dried not fresh), and a touch of salt it's a yummy yogurt salad
Very similar to the greek sauce you put on gyros- but definitely healthier! I cut up a whole cucumber, put in a cup of yogurt- give or take- I want enough to coat the yogurt but not overwhelm, and mix in my salt and dill- HEAVEN!
