If you're intrigued by the speckled borlotti beans at the farmers' market, this minestrone is the perfect excuse to grab a few pounds. The hearty soup is flexible by nature—think of the ingredients as mere suggestions. Didn't find borlottis? Use butter beans instead, or canned versions of either. No escarole or kale in sight? Toss in another leafy green—say, mustard greens or chard. Last, stir in cooked pasta; any shape you can eat with a spoon will do!
