I made this for a cookout for myself and two of my friends who were also watching what they eat. This was actually gone before the regular pasta salad! I love the idea of using half mayo and half yogurt instead of all mayo, it cuts the calories and fat but doesn't affect the flavor very much. I did make some modifications: I used the juice of one lemon as well as the zest for more flavor, and also added a packet of the Wishbone Italian salad dressing mix. I don't like peppers so I left them out but added more tomatoes and carrots to compensate. The second time I made this, I added in broccoli and cucumbers as well, and added 2 lemons so I could stretch the dressing without adding calories.
