Pesto Minestrone Soup
This summer delight is a version of minestrone with the flavors of pesto: lots of basil and some nuts, even cheese stirred in at the end. We didn’t sauté the onions and other vegetables first because we wanted a cleaner, brighter flavor. The soup’s actually a bit sour, best on a warm evening (with a G&T—trust us). Calm it down with lots of crunchy bread to sop up every drop.
