Good and good for you

So, at least until Vegas, I'm doing my best to trade alcohol for hot green tea and junk food for salads. The good thing is that salads can be really yummy with just a little effort. The one I made the other day for lunch practically felt like a guilty splurge!
Maybe this healthy eating thing wont be so hard after all....

Spring mix, tomatoes (I love the kind you can buy still on the vine), avocado, feta cheese, and just a splash of 

Wishbone's Olive Oil Vinaigrette.

What are some of your favorite, easy salads to create at home?
