1. Sliced boiled red potatoes ("A" size) and haricots verts al dente in a nice vinagrette (w a little Dijon mustard) topped with a few sliced Kalamata olives) and a sprinkling of Feta atop some Spring Greens, Arugula, baby Spinach, etc.

2. The "White" potato salad (inc. sour cream and chopped dill) at Uncle Dan's BBQ in Waco.
