Made for Spring PAC 2013 - What I like most about pasta salads is they are flexible & easily allow for pers pref. What I liked most about this pasta salad is it is veggie-rich & uses sour cream vs mayo. Mayo is 80% fat (per internet sources). I used a 5% fat sour cream & did not feel at all deprived due to the goodness of the other salad ingredients (both flavor & texture). I did not have tri-color pasta, so I used a sml shell pasta & made the recipe exactly as written except for adding corn kernels left from another recipe. I think baby shrimp would also work well, but I would be liberal w/Old Bay Seasoning in that case. I am so glad I found Princelings recipe. Besides being downright good & satisfying as a main-meal w/just fruit, it is a sure-fire all-occasion crowd-pleaser for luncheon guests, pot-luck, picnics, patio parties, etc. Thx for sharing this recipe w/us.
