Combine first 8 ingredients in a large bowl; toss well. Sprinkle with cracked black pepper, if desired.
Wine note: With the simple, fresh flavors of this cavatappi dish, look for a light, refreshing Italian pinot grigio that also has northern Italian heritage. Bollini Pinot Grigio Trentino 2005 ($15) has flavors of white peach and nectarine. The juicy, refreshing quality is perfect against the dry texture of the beans and the slightly bitter spinach, while the rather full body matches the olive oil's fruity richness. --Jeffery Lindenmuth
